[0001] This application relates to the field of digital transmitter technology, and more specifically, to a method, apparatus, and electronic device for adjusting the transmission power range. Background Technology

[0002] A fully digital transmitter is a transmitter implementation based on digital algorithms and using standard digital gates (STD CELLs) as the main internal modules (or basic units). It is a circuit architecture that, with the appropriate output power matching module, can achieve the same operating principle (radio frequency signal transmission) as an analog transmitter. However, in existing fully digital transmitters, the dynamic range of their transmit power is generally relatively small. Summary of the Invention

[0003] The purpose of this application is to provide a method, apparatus, and electronic device for adjusting the transmission power range, so as to solve the technical problem of the small dynamic range of transmission power of digital transmitters in the prior art.

[0004] In a first aspect, embodiments of this application provide a method for adjusting the transmission power range, applied to a control module in a digital transmitter. The digital transmitter further includes at least one transmission module, each transmission module including multiple basic units, wherein the basic unit includes a switched capacitor circuit based on multiple supply voltages. The method for adjusting the transmission power range includes: determining, based on the initial transmission power range and the target transmission power range of the digital transmitter, the number of transmission modules that are turned on, the supply voltage of the basic units in the turned-on transmission modules, and an additional bit control signal for controlling the number of transmission modules that are turned on and the supply voltage of the basic units, so as to adjust the corresponding transmission power range of the digital transmitter.

[0005] In the above scheme, the transmission power range of the digital transmitter can be adjusted by changing the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules. In particular, by adding a bit control signal to perform corresponding dynamic and / or static control on the above adjustment, a larger dynamic range of transmission power of the digital transmitter can be achieved.

[0006] In an optional implementation, determining the number of conducting transmitter modules, the supply voltage of the basic units in the conducting transmitter modules, and the additional bit control signal for controlling the number of conducting transmitter modules and the supply voltage of the basic units based on the initial and target transmit power ranges of the digital transmitter, includes: when the upper limit of the target transmit power range is Q dB greater than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is equal to the lower limit of the initial transmit power range, determining, according to at least one of the following formulas, that the number of conducting transmitter modules is m times the number of conducting transmitter modules corresponding to the initial transmit power range, and that the supply voltage of some basic units in the conducting transmitter modules is n times the supply voltage corresponding to the initial transmit power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range: when the additional bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic units, the parameters Q, m, and n satisfy the following formula:

[0007] Q = 10 × lg(n) 2 ), m = 1;

[0008] When a new bit control signal is used to control the dynamic change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0009] Q = 10 × lg(m), n = 1;

[0010] When the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0011] Q = 10 × lg(n) 2 ·m).

[0012] In the above scheme, if the upper limit of the target transmission power range is larger than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, it can be considered that both the transmission power accuracy corresponding to the digital transmitter and the window position of the transmission power are adjusted at this time. At this time, by adjusting the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules, and by using the newly added bit control signal to control the adjustment of the transmission power window length corresponding to the digital transmitter, the dynamic adjustment of the transmission power accuracy corresponding to the digital transmitter can be realized, thereby achieving a larger dynamic range of transmission power for the digital transmitter.

[0013] In an optional implementation, if Q = 6, m = 1, n = 2, then for each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added to control the dynamic switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 4, n = 1, then for each basic unit in the activated transmitter module, the supply voltage corresponding to all basic units is the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added to control the dynamic change of the number of activated transmitter modules.

[0014] In an optional implementation, determining the number of conducting transmitter modules, the supply voltage of the basic units in the conducting transmitter modules, and a new bit control signal for controlling the number of conducting transmitter modules and the supply voltage of the basic units based on the initial and target transmit power ranges of the digital transmitter, includes: when the lower limit of the target transmit power range is QdB greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, determining, according to at least one of the following formulas, that the number of conducting transmitter modules is m times the number of conducting transmitter modules corresponding to the initial transmit power range, and the supply voltage of some basic units in the conducting transmitter modules is n times the supply voltage corresponding to the initial transmit power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range: when the new bit control signal is used to control the static switching of the supply voltage corresponding to the basic units, the parameters Q, m, and n satisfy the following formula:

[0015] Q = 10 × lg(n) 2 ), m = 1;

[0016] When a new bit control signal is used to control the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0017] Q = 10 × lg(m), n = 1;

[0018] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0019] Q = 10 × lg(n) 2 ·m).

[0020] In the above scheme, if the lower limit of the target transmit power range is QdBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdBm greater than the upper limit of the initial transmit power range, it can be considered that only the window position of the transmit power is adjusted at this time. At this time, by adjusting the number of transmit modules in the digital transmitter and the power supply voltage of the basic unit in the transmit modules, and by using the newly added bit control signal to control the adjustment of the corresponding transmit power window position of the digital transmitter, the static adjustment of the corresponding transmit power window position of the digital transmitter can be achieved, thereby realizing a larger dynamic range of transmit power of the digital transmitter.

[0021] In an optional implementation, if Q = 6, m = 1, and n = 2, then for each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added, which is used to control the static switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 2, For each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is [missing value]. The number of bits is increased by 10 times; among them, two new bit control signals are added, one bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conduction bits of the transmitting module.

[0022] In an optional implementation, the step of determining the number of conducting transmitter modules, the supply voltage of the basic units in the conducting transmitter modules, and the additional bit control signal for controlling the number of conducting transmitter modules and the supply voltage of the basic units based on the initial and target transmit power ranges of the digital transmitter includes: when the lower limit of the target transmit power range is PdB greater than the lower limit of the initial transmit power range, the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, and Q>P, the number of conducting transmitter modules is determined to be m times the number of conducting transmitter modules corresponding to the initial transmit power range, and the supply voltage of some basic units in the conducting transmitter modules is n times the supply voltage corresponding to the initial transmit power range, according to at least one of the following formulas: where the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range; when the additional bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic units and the static change of the number of conducting transmitter modules, the parameters Q, P, m, and n satisfy the following formula:

[0023] Q = 10 × lg(n) 2 ·m), P=10×lg(m);

[0024] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules, the parameters Q, P, m, and n satisfy the following formula:

[0025] Q = 10 × lg(n) 2 ·m), P=10×lg(n 2 ).

[0026] In the above scheme, if the lower limit of the target transmit power range is P dBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is Q dBm greater than the upper limit of the initial transmit power range, and Q>P, it can be considered that both the transmit power accuracy corresponding to the digital transmitter and the window position of the transmit power are adjusted at this time. At this time, by adjusting the number of conduction modules in the digital transmitter and the power supply voltage of the basic unit in the conduction module, and by using the newly added bit control signal to control the adjustment of the transmit power window length and the transmit power window position corresponding to the digital transmitter, the transmit power accuracy and window position corresponding to the digital transmitter can be adjusted simultaneously, thereby achieving a larger dynamic range of transmit power for the digital transmitter.

[0027] In an optional implementation, if P = 3, Q = 9, m = 2, n = 2, then for each basic unit in a conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, two additional bit control signals are added, one bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules; or, if P = 6, Q = 12, m = 4, n = 2, then for each basic unit in a conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, two additional bit control signals are added, one bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules.

[0028] Secondly, embodiments of this application provide a transmission power range adjustment device applied to a control module in a digital transmitter. The digital transmitter further includes at least one transmission module, each transmission module including multiple basic units, wherein the basic unit includes a switched capacitor circuit based on multiple supply voltages. The transmission power range adjustment device includes: a determining module, used to determine, based on the initial transmission power range and target transmission power range of the digital transmitter, the number of transmission modules in operation, the supply voltage of the basic units in the in operation transmission modules, and an additional bit control signal for controlling the number of transmission modules in operation and the supply voltage of the basic units, so as to adjust the corresponding transmission power range of the digital transmitter.

[0029] In the above scheme, the transmission power range of the digital transmitter can be adjusted by changing the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules. In particular, by adding a bit control signal to perform corresponding dynamic and / or static control on the above adjustment, a larger dynamic range of transmission power of the digital transmitter can be achieved.

[0030] In an optional implementation, the determining module is specifically configured to: when the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is equal to the lower limit of the initial transmit power range, determine, according to at least one of the following formulas, that the number of conduction modules is m times the number of conduction modules corresponding to the initial transmit power range, and the supply voltage of a portion of the basic units in the conduction modules is n times the supply voltage corresponding to the initial transmit power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range: when a new bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic units, the parameters Q, m, and n satisfy the following formula:

[0031] Q = 10 × lg(n) 2 ), m = 1;

[0032] When a new bit control signal is used to control the dynamic change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0033] Q = 10 × lg(m), n = 1;

[0034] When the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0035] Q = 10 × lg(n) 2·m).

[0036] In the above scheme, if the upper limit of the target transmission power range is larger than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, it can be considered that at this time, both the transmission power accuracy corresponding to the digital transmitter and the window position of the transmission power are adjusted, that is, the transmission power window length corresponding to the digital transmitter is adjusted. At this time, by adjusting the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules, and using the newly added bit control signal to control the adjustment of the transmission power window length corresponding to the digital transmitter, the dynamic adjustment of the transmission power accuracy corresponding to the digital transmitter can be realized, thereby achieving a larger dynamic range of transmission power for the digital transmitter.

[0037] In an optional implementation, if Q = 6, m = 1, n = 2, then for each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added to control the dynamic switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 4, n = 1, then for each basic unit in the activated transmitter module, the supply voltage corresponding to all basic units is the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added to control the dynamic change of the number of activated transmitter modules.

[0038] In an optional implementation, the determining module is specifically configured to: when the lower limit of the target transmit power range is QdB greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, determine, according to at least one of the following formulas, that the number of conduction modules is m times the number of conduction modules corresponding to the initial transmit power range, and the supply voltage of a portion of the basic units in the conduction modules is n times the supply voltage corresponding to the initial transmit power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range: when a new bit control signal is used to control the static switching of the supply voltage corresponding to the basic unit, the parameters Q, m, and n satisfy the following formula:

[0039] Q = 10 × lg(n) 2 ), m = 1;

[0040] When a new bit control signal is used to control the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0041] Q = 10 × lg(m), n = 1;

[0042] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0043] Q = 10 × lg(n) 2 ·m).

[0044] In the above scheme, if the lower limit of the target transmit power range is QdBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdBm greater than the upper limit of the initial transmit power range, it can be considered that only the window position of the transmit power is adjusted at this time. At this time, by adjusting the number of transmit modules in the digital transmitter and the power supply voltage of the basic unit in the transmit modules, and by using the newly added bit control signal to control the adjustment of the corresponding transmit power window position of the digital transmitter, the static adjustment of the corresponding transmit power window position of the digital transmitter can be achieved, thereby realizing a larger dynamic range of transmit power of the digital transmitter.

[0045] In an optional implementation, if Q = 6, m = 1, and n = 2, then for each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added, which is used to control the static switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 2, For each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is [missing value]. The number of bits is increased by 10 times; among them, two new bit control signals are added, one bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conduction bits of the transmitting module.

[0046] In an optional implementation, the determining module is specifically configured to: when the lower limit of the target transmit power range is PdB greater than the lower limit of the initial transmit power range, the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, and Q>P, determine, according to at least one of the following formulas, that the number of conduction modules is m times the number of conduction modules corresponding to the initial transmit power range, and the supply voltage of a portion of the basic units in the conduction modules is n times the supply voltage corresponding to the initial transmit power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range; when a new bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic units and the static change of the number of conduction modules, the parameters Q, P, m, and n satisfy the following formula:

[0047] Q = 10 × lg(n) 2 ·m), P=10×lg(m);

[0048] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules, the parameters Q, P, m, and n satisfy the following formula:

[0049] Q = 10 × lg(n) 2 ·m), P=10×lg(n 2 ).

[0050] In the above scheme, if the lower limit of the target transmit power range is P dBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is Q dBm greater than the upper limit of the initial transmit power range, and Q>P, it can be considered that both the transmit power accuracy corresponding to the digital transmitter and the window position of the transmit power are adjusted at this time. At this time, by adjusting the number of conduction modules in the digital transmitter and the power supply voltage of the basic unit in the conduction module, and by using the newly added bit control signal to control the adjustment of the transmit power window length and the transmit power window position corresponding to the digital transmitter, the transmit power accuracy and window position corresponding to the digital transmitter can be adjusted simultaneously, thereby achieving a larger dynamic range of transmit power for the digital transmitter.

[0051] In an optional implementation, if P = 3, Q = 9, m = 2, n = 2, then for each basic unit in a conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, two additional bit control signals are added, one bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules; or, if P = 6, Q = 12, m = 4, n = 2, then for each basic unit in a conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, two additional bit control signals are added, one bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules.

[0064] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0065] Please refer to Figure 1 , Figure 1 This application provides a structural block diagram of a digital transmitter 100, which may include a control module 101 and at least one transmission module 102. Each transmission module 102 includes multiple basic units, and each basic unit includes a switched capacitor circuit based on multiple supply voltages. The control module is used to execute the transmission power range adjustment method provided in this application embodiment.

[0066] Please refer to Figure 2 , Figure 2 This is a schematic diagram of a digital transmitter provided in an embodiment of this application. As one implementation, the basic unit may include: a first P-type MOSFET, whose source (S) receives a first input voltage; a second P-type MOSFET, whose source (S) is connected to the drain (D) of the first P-type MOSFET; a first N-type MOSFET, whose source (S) is grounded; a second N-type MOSFET, whose source (S) is connected to the drain (D) of the first N-type MOSFET, and whose drain (D) is connected to the drain (D) of the second P-type MOSFET; and a third P-type MOSFET, whose source (S) receives a second input voltage, and whose drain (D) is connected to the source (S) of the second P-type MOSFET.

[0067] It should be noted that the embodiments of this application do not specifically limit the magnitude of the first input voltage and the second input voltage, and those skilled in the art can make appropriate adjustments according to the actual situation. For example, the first input voltage can be twice the second input voltage; or, the first input voltage can be three times the second input voltage, etc.

[0068] Please refer to Figure 3 , Figure 4 , Figure 3 This is a schematic diagram illustrating dynamic control of a digital transmitter, provided as an embodiment of this application. Figure 4 This is a schematic diagram illustrating static control of a digital transmitter, provided as an embodiment of this application.

[0069] It can be seen that, Figure 2 In the digital transmitter, there is a transmission module combined linkage control 1a for controlling the conduction or disconnection of the first P-type MOSFET P1; combined linkage control 1b for controlling the conduction or disconnection of the third P-type MOSFET P3; combined linkage control 2 for controlling the conduction or disconnection of the second P-type MOSFET P2 and the second N-type MOSFET N2; combined linkage control 3 for controlling the conduction or disconnection of the first N-type MOSFET N1; the first input voltage is 2Vdd, and the second input voltage is Vdd.

Figure 3 ;exist Figure 3 In this circuit, when the input logic is 0, P1 inputs 2Vdd, and P2, N1, and N2 all input Vdd. At this time, P1 is off, and Vo = 0. When the input logic is 1, P1, P2, and N2 all input Vdd, and N1 inputs 0. At this time, P1 is on, and Vo = 2Vdd. The inputs of P1 and N1 are dynamic, while the inputs of P2 and N2 are static.

Figure 4 ;exist Figure 4 In this circuit, when the input logic is 0, P3 inputs 0, and P2, N1, and N2 all input Vdd. At this time, P3 is turned on, and Vo = 0. When the input logic is 1, P3, P2, and N2 all input 0, and N1 inputs Vdd. At this time, P3 is turned on, and Vo = Vdd. The inputs of P2 and N2 are dynamic, while the inputs of P3 and N1 are static.

[0072] Please refer to Figure 5 , Figure 5This is a schematic diagram of another digital transmitter provided in an embodiment of this application. In this case, the digital transmitter includes multiple transmission modules. Specifically, when X1 is turned on, one transmission module of the digital transmitter is turned on; when X2 is turned on, two transmission modules of the digital transmitter are turned on; and when X4 is turned on, all four transmission modules of the digital transmitter are turned on.

[0073] It should be noted that when a digital transmitter includes multiple transmission modules, the embodiments of this application do not specifically limit the specific structure of the aforementioned multiple transmission modules. Taking X2 as an example, in one implementation, X2 includes two independent transmission modules with identical structures; in another implementation, X2 is composed of two transmission modules combined into one module, which includes two connected P1, two connected P2, two connected P3, two connected N1, and two connected N2.

[0074] Based on the aforementioned digital transmitter, in one implementation, the transmission power range of the digital transmitter can be adjusted by static or dynamic control through adjusting the power supply voltage of the base unit; in another implementation, the transmission power range of the digital transmitter can also be adjusted by static or dynamic control through adjusting the number of conducting elements of the transmission module; in yet another implementation, the transmission power range of the digital transmitter can also be adjusted by static or dynamic control through simultaneously adjusting the power supply voltage of the base unit and the number of conducting elements of the transmission module.

[0075] Please refer to Figure 6 , Figure 6 The flowchart illustrates a method for adjusting the transmission power range according to an embodiment of this application. This method is applied to the control module of the aforementioned digital transmitter and may include the following steps:

[0076] Step S601: Based on the initial transmit power range and target transmit power range of the digital transmitter, determine the number of conduction modules, the power supply voltage of the basic unit in the conduction module, and the newly added bit control signal used to control the number of conduction modules and the power supply voltage of the basic unit, so as to adjust the corresponding transmit power range of the digital transmitter.

[0077] Specifically, the initial transmit power range of a digital transmitter refers to the transmit power range of the digital transmitter before the transmit power range of the digital transmitter is adjusted; correspondingly, the target transmit power range of a digital transmitter refers to the transmit power range of the digital transmitter after the transmit power range of the digital transmitter is adjusted.

[0078] Therefore, by comparing the relationship between the upper limit of the initial transmit power range and the upper limit of the target transmit power range of the digital transmitter, as well as the relationship between the lower limit of the initial transmit power range and the lower limit of the target transmit power range of the digital transmitter, it is possible to determine what adjustments need to be made to the transmit power range of the digital transmitter.

[0079] As one implementation method, if the upper limit of the target transmit power range is larger than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is equal to the lower limit of the initial transmit power range, it can be considered that both the transmit power accuracy corresponding to the digital transmitter and the transmit power window position are adjusted. For example, the initial transmit power range is [-72, 0] dB, and the target transmit power range is [-72, 6] dB. In this case, the transmit power window length of the digital transmitter can be adjusted by combining dynamic switching of the power supply voltage corresponding to the basic unit and dynamic changing of the number of conducting elements in the transmit module.

[0080] As another implementation, if the upper limit of the target transmit power range is larger than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is also larger than the lower limit of the initial transmit power range, and the extent to which the upper limit is larger is equal to the extent to which the lower limit is larger, it can be assumed that only the transmit power window position corresponding to the digital transmitter is adjusted. For example, if the initial transmit power range is [-72, 0] dB and the target transmit power range is [-66, 6] dB, then the transmit power window position of the digital transmitter can be adjusted by combining static switching of the power supply voltage corresponding to the basic unit and static change of the number of conducting elements in the transmit module.

[0081] As another implementation method, if the upper limit of the target transmit power range is larger than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is larger than the lower limit of the initial transmit power range, and the extent to which the upper limit is larger is greater than the extent to which the lower limit is larger, it can be considered that both the transmit power window length and the transmit power window position corresponding to the digital transmitter are adjusted. For example, if the initial transmit power range is [-72, 0] dB and the target transmit power range is [-69, 9] dB, then the transmit power window length and position of the digital transmitter can be adjusted simultaneously by combining static switching of the power supply voltage corresponding to the basic unit with dynamic changes to the number of conducting elements in the transmit module.

[0082] In this embodiment, the transmit power range of the digital transmitter is adjusted by adjusting the number of conduction modules and the power supply voltage of the basic unit in the conduction module, and by using a newly added bit control signal to control the change of the number of conduction modules and / or the switching of the power supply voltage.

[0083] Therefore, based on the initial and target transmit power ranges of the digital transmitter, after determining the number of conducting transmitter modules, the power supply voltage of the basic units in the conducting transmitter modules, and the newly added bit control signals, the corresponding transmit power range of the digital transmitter can be adjusted.

[0084] It should be noted that the embodiments of this application do not impose specific limitations on the specific implementation of determining the number of conducting transmitter modules, the power supply voltage of the basic unit in the conducting transmitter module, and the newly added bit control signal. Those skilled in the art can make appropriate adjustments according to the actual situation.

[0085] Furthermore, as one implementation, only the number of conducting transmitter modules can be adjusted; as another implementation, only the power supply voltage of the base unit in the conducting transmitter module can be adjusted; as yet another implementation, both the number of conducting transmitter modules and the power supply voltage of the base unit in the conducting transmitter module can be adjusted simultaneously; the embodiments of this application do not impose specific limitations on this.

[0086] In the above scheme, the transmission power range of the digital transmitter can be adjusted by changing the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules. In particular, by adding a bit control signal to perform corresponding dynamic and / or static control on the above adjustment, a larger dynamic range of transmission power of the digital transmitter can be achieved.

[0087] Furthermore, based on the above implementation method, step S601 may include the following steps:

[0088] When the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is equal to the lower limit of the initial transmit power range, the number of conduction modules in the transmit module is determined to be m times the number of conduction modules corresponding to the initial transmit power range, and the supply voltage of some basic units in the conduction module is n times the supply voltage corresponding to the initial transmit power range, according to at least one of the following formulas, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range.

[0089] Specifically, if the upper limit of the target transmission power range is larger than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, it can be assumed that both the transmission power accuracy corresponding to the digital transmitter and the window position of the transmission power are adjusted, i.e., the transmission power window length corresponding to the digital transmitter is adjusted. Therefore, the purpose of adjusting the transmission power window length of the digital transmitter can be achieved by combining the dynamic switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules.

[0090] Based on the power calculation formula: power equals the square of voltage divided by resistance. Therefore, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the supply voltage needs to be increased by 2 times. Similarly, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the number of conducting elements needs to be increased by 4 times.

[0091] As one implementation, when the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit, the parameters Q, m, and n can satisfy the following formula:

[0092] Q = 10 × lg(n) 2 ), m=1.

[0093] In another implementation, when the newly added bit control signal is used to control the dynamic change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0094] Q = 10 × lg(m), n = 1.

[0095] In another implementation, when the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conducting elements of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0096] Q = 10 × lg(n) 2 ·m).

[0097] In the above scheme, if the upper limit of the target transmission power range is larger than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, it can be considered that at this time, both the transmission power accuracy corresponding to the digital transmitter and the window position of the transmission power are adjusted, that is, the transmission power window length corresponding to the digital transmitter is adjusted. At this time, by adjusting the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules, and using the newly added bit control signal to control the adjustment of the transmission power window length corresponding to the digital transmitter, the dynamic adjustment of the transmission power accuracy corresponding to the digital transmitter can be realized, thereby achieving a larger dynamic range of transmission power for the digital transmitter.

[0098] Furthermore, based on the above implementation method, if Q=6, m=1, n=2, then for each basic unit in the conducting transmitter module, the power supply voltage corresponding to one basic unit is the power supply voltage corresponding to the initial transmitter power range, and the power supply voltage corresponding to other basic units is twice the power supply voltage corresponding to the initial transmitter power range; wherein, a new bit control signal is added, which is used to control the dynamic switching of the power supply voltage corresponding to the basic unit.

[0099] Specifically, in this implementation, only one transmitting module is in the conducting state. For each conducting transmitting module's basic unit, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmitting power range, while the supply voltage corresponding to the other basic units is twice the supply voltage corresponding to the initial transmitting power range. By keeping the supply voltage of one basic unit constant while changing the supply voltages of the other basic units, minimum power output can be maintained; in other words, the lower limit of the target transmitting power range can be kept the same as the lower limit of the initial transmitting power range.

[0100] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dBm = 72 dB. Assuming a = -72 dB and b = 0 dB, in this case, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-72, 6] dB, a bit control signal b12 can be added. At this time, it is in the X1 state (controlling one transmit module to be turned on). b12 controls one basic unit in X1 to be in Vdd, and the other basic units to be in 2Vdd.

[0101] Furthermore, based on the above implementation method, if Q=6, m=4, n=1, then for each basic unit in the conducting transmitter module, the power supply voltage corresponding to all basic units is the power supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added, which is used to control the dynamic change of the number of conducting transmitter modules.

[0102] Specifically, in this implementation, four transmitting modules are in the conducting state; for each conducting transmitting module, the power supply voltage corresponding to all basic units is the power supply voltage corresponding to the initial transmitting power range.

[0103] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dBm = 72 dB. Assuming a = -72 dB and b = 0 dB, in this case, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-72, 6] dB, a bit control signal b12 can be added. At this time, it is in X4 state (controlling the conduction of four transmit modules). b12 controls all basic units in X4 to be in Vdd.

[0104] Furthermore, based on the above implementation method, step S601 may include the following steps:

[0105] When the lower limit of the target transmit power range is QdB greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, the number of conduction modules in the transmit module is determined according to at least one of the following formulas: m times the number of conduction modules corresponding to the initial transmit power range; the supply voltage of some basic units in the conduction module is n times the supply voltage corresponding to the initial transmit power range; and the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range.

[0106] Specifically, if the upper limit of the target transmit power range is larger than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is equal to the lower limit of the initial transmit power range, and the extent to which the upper limit is larger is equal to the extent to which the lower limit is larger, it can be assumed that only the window position of the transmit power corresponding to the digital transmitter is adjusted. Therefore, the purpose of adjusting the transmit power window position of the digital transmitter can be achieved by combining static switching of the power supply voltage corresponding to the basic unit and static change of the number of conduction modules.

[0107] Based on the same formula for power calculation: power equals the square of voltage divided by resistance, therefore, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the supply voltage needs to be increased by 2 times; similarly, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the number of conducting elements needs to be increased by 4 times.

[0108] As one implementation, when the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit, the parameters Q, m, and n satisfy the following formula:

[0109] Q = 10 × lg(n) 2 ), m = 1;

[0110] In another implementation, when the newly added bit control signal is used to control the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0111] Q = 10 × lg(m), n = 1;

[0112] In another implementation, when the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0113] Q = 10 × lg(n) 2 ·m).

[0114] In the above scheme, if the lower limit of the target transmit power range is QdBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdBm greater than the upper limit of the initial transmit power range, it can be considered that only the window position of the transmit power is adjusted at this time. At this time, by adjusting the number of transmit modules in the digital transmitter and the power supply voltage of the basic unit in the transmit modules, and by using the newly added bit control signal to control the adjustment of the corresponding transmit power window position of the digital transmitter, the static adjustment of the corresponding transmit power window position of the digital transmitter can be achieved, thereby realizing a larger dynamic range of transmit power of the digital transmitter.

[0115] Furthermore, based on the above implementation, if Q=6, m=1, n=2, then for each basic unit in the conducting transmitter module, the power supply voltage corresponding to one basic unit is the power supply voltage corresponding to the initial transmitter power range, and the power supply voltage corresponding to other basic units is twice the power supply voltage corresponding to the initial transmitter power range; wherein, a new bit control signal is added, which is used to control the static switching of the power supply voltage corresponding to the basic unit.

[0116] Specifically, in this implementation, one transmitting module is in a conducting state; for each basic unit in the conducting transmitting module, the power supply voltage corresponding to one basic unit is the power supply voltage corresponding to the initial transmitting power range, and the power supply voltage corresponding to other basic units is twice the power supply voltage corresponding to the initial transmitting power range.

[0117] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dBm = 72 dBm. Assuming a = -72 dBm and b = 0 dBm: at this time, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-66, 6] dB, a bit control signal b12 can be added. In this case, b12 controls one basic unit in each transmit module to be at Vdd, and the other basic units to be at 2Vdd.

[0118] Furthermore, based on the above implementation method, if Q = 6 and m = 2, For each basic unit in the conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is the supply voltage corresponding to the initial transmit power range. The system is configured to multiply by 100%. Two additional control bits are added: one for controlling the static switching of the power supply voltage corresponding to the basic unit, and the other for controlling the static change in the number of conducting elements of the transmitting module. Since the two additional control bits have the same function, in other embodiments, they can be implemented as a single additional control bit.

[0119] Specifically, in this implementation, both transmitting modules are in a conducting state; for each conducting transmitting module's basic unit, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to the other basic units is [missing information - likely a percentage] of the supply voltage corresponding to the initial transmit power range. times.

[0120] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dBm = 72 dBm. Assuming a = -72 dBm and b = 0 dBm: at this time, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-66, 6] dB, bit control signals b12 and b13 can be added. In this case, b12 controls one basic unit in each transmit module to be in the state of... Other basic units are in Vdd, and the b13 control is in X2 state (controlling the conduction of the two transmitter modules).

[0121] Furthermore, based on the above implementation method, step S601 may include the following steps:

[0122] When the lower limit of the target transmit power range is PdB greater than the lower limit of the initial transmit power range, the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, and Q>P, the number of conduction modules in the transmit module is determined according to at least one of the following formulas: m times the number of conduction modules corresponding to the initial transmit power range; the supply voltage of some basic units in the conduction module is n times the supply voltage corresponding to the initial transmit power range; and the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmit power range.

[0123] Specifically, if the upper limit of the target transmit power range is larger than the upper limit of the initial transmit power range, and the lower limit of the target transmit power range is larger than the lower limit of the initial transmit power range, and the extent to which the upper limit is larger is greater than the extent to which the lower limit is larger, it can be assumed that both the transmit power window length and the transmit power window position of the digital transmitter are adjusted. Therefore, the purpose of simultaneously adjusting the transmit power window length and position of the digital transmitter can be achieved by combining static switching of the power supply voltage corresponding to the basic unit with dynamic changes to the number of conduction modules.

[0124] Based on the same formula for power calculation: power equals the square of voltage divided by resistance, therefore, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the supply voltage needs to be increased by 2 times; similarly, when the transmit power of a digital transmitter needs to be increased by 6dB, the power needs to be increased by 4 times, and correspondingly, the number of conducting elements needs to be increased by 4 times.

[0125] As one implementation, when the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the static change of the number of conduction modules of the transmitting module, the parameters Q, P, m, and n satisfy the following formula:

[0126] Q = 10 × lg(n) 2 ·m), P=10×lg(m);

[0127] In another implementation, when the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules, the parameters Q, P, m, and n satisfy the following formula:

[0128] Q = 10 × lg(n) 2·m), P=10×lg(n 2 ).

[0129] In the above scheme, if the lower limit of the target transmit power range is P dBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is Q dBm greater than the upper limit of the initial transmit power range, and Q>P, it can be considered that both the transmit power accuracy corresponding to the digital transmitter and the window position of the transmit power are adjusted at this time. At this time, by adjusting the number of conduction modules in the digital transmitter and the power supply voltage of the basic unit in the conduction module, and by using the newly added bit control signal to control the adjustment of the transmit power window length and the transmit power window position corresponding to the digital transmitter, the transmit power accuracy and window position corresponding to the digital transmitter can be adjusted simultaneously, thereby achieving a larger dynamic range of transmit power for the digital transmitter.

[0130] Furthermore, based on the above implementation, if P=3, Q=9, m=2, n=2, then for each basic unit in the conducting transmitter module, the power supply voltage corresponding to one basic unit is the power supply voltage corresponding to the initial transmit power range, and the power supply voltage corresponding to other basic units is twice the power supply voltage corresponding to the initial transmit power range; wherein, two new bit control signals are added, one bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules.

[0131] Specifically, in this implementation, for each basic unit in the conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range.

[0132] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dB = 72 dB. Assuming a = -72 dB and b = 0 dBm, in this case, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-69, 9] dB, then, based on increasing the precision by 1 bit, the static range of transmit power can be changed by 0.5 bits. This can be achieved by adding bit control signals b12 and b13. At this time, b12 controls the two basic units in X2 to be in Vdd, and the other basic units to be in 2Vdd. b13 controls the X2 state (controlling the two transmit modules to be turned on).

[0133] Furthermore, based on the above implementation, if P=6, Q=12, m=4, n=2, then for each basic unit in the conducting transmitter module, the power supply voltage corresponding to one basic unit is the power supply voltage corresponding to the initial transmit power range, and the power supply voltage corresponding to other basic units is twice the power supply voltage corresponding to the initial transmit power range; wherein, two new bit control signals are added, one bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conducting transmitter modules.

[0134] Specifically, in this implementation, for each basic unit in the conducting transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range.

[0135] For example, assuming the initial transmit power range is [a, b] dB, and the initial bit control signal is a 12-bit control signal corresponding to b0-b11, then ba = 12 × 6 dB = 72 dB. Assuming a = -72 dB and b = 0 dB, in this case, a transmit module includes 2... 12 = 4096 basic units. If the target transmit power range is [-66, 12] dB, then, by increasing the precision by 1 bit, the transmit power range can be changed by 1 bit. This can be achieved by adding bit control signals b12 and b13. At this time, b12 controls the four basic units in X4 to be in Vdd, and the other basic units to be in 2Vdd. b13 controls the state to be in X4 (controlling the four transmit modules to be turned on).

[0136] Alternatively, bit control signals b12, b13, and b14 can be added. In this case, b12 controls the four basic units in X4 to be in Vdd, and the other basic units to be in 2Vdd. b13 and b14 control the state to be in X4 (controlling the two transmitter modules to be turned on).

[0137] Please refer to Figure 7 , Figure 7This is a structural block diagram of a transmission power range adjustment device provided in an embodiment of this application. The transmission power range adjustment device 700 is applied to the control module of a digital transmitter. The digital transmitter further includes at least one transmission module, each transmission module including multiple basic units, wherein the basic unit includes a switched capacitor circuit based on multiple supply voltages. The transmission power range adjustment device 700 includes: a determining module 701, used to determine the number of transmission modules in operation, the supply voltage of the basic units in the in operation transmission modules, and an additional bit control signal for controlling the number of transmission modules in operation and the supply voltage of the basic units, based on the initial transmission power range and the target transmission power range of the digital transmitter, so as to adjust the corresponding transmission power range of the digital transmitter.

[0138] In the above scheme, the transmission power range of the digital transmitter can be adjusted by changing the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules. In particular, by adding a bit control signal to perform corresponding dynamic and / or static control on the above adjustment, a larger dynamic range of transmission power of the digital transmitter can be achieved.

[0139] Furthermore, based on the above implementation, the determining module 701 is specifically used to: when the upper limit of the target transmission power range is QdB greater than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, determine, according to at least one of the following formulas, that the number of conducting units of the transmission module is m times the number of conducting units corresponding to the initial transmission power range, and that the supply voltage of some basic units in the conducting transmission module is n times the supply voltage corresponding to the initial transmission power range, wherein the supply voltage of the remaining basic units is the supply voltage corresponding to the initial transmission power range: when the newly added bit control signal is used to control the dynamic switching of the supply voltage corresponding to the basic unit, the parameters Q, m, and n satisfy the following formula:

[0140] Q = 10 × lg(n) 2 ), m = 1;

[0141] When a new bit control signal is used to control the dynamic change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0142] Q = 10 × lg(m), n = 1;

[0143] When the newly added bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0144] Q = 10 × lg(n) 2 ·m).

[0145] In the above scheme, if the upper limit of the target transmission power range is larger than the upper limit of the initial transmission power range, and the lower limit of the target transmission power range is equal to the lower limit of the initial transmission power range, it can be considered that at this time, both the transmission power accuracy corresponding to the digital transmitter and the window position of the transmission power are adjusted, that is, the transmission power window length corresponding to the digital transmitter is adjusted. At this time, by adjusting the number of conducting transmission modules in the digital transmitter and the power supply voltage of the basic unit in the conducting transmission modules, and using the newly added bit control signal to control the adjustment of the transmission power window length corresponding to the digital transmitter, the dynamic adjustment of the transmission power accuracy corresponding to the digital transmitter can be realized, thereby achieving a larger dynamic range of transmission power for the digital transmitter.

[0146] Furthermore, based on the above implementation, if Q = 6, m = 1, n = 2, then for each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added, which is used to control the dynamic switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 4, n = 1, then for each basic unit in the activated transmitter module, the supply voltage corresponding to all basic units is the supply voltage corresponding to the initial transmit power range; wherein, a new bit control signal is added, which is used to control the dynamic change of the number of activated transmitter modules.

[0147] Furthermore, based on the above implementation, the determining module 701 is specifically used to: when the lower limit of the target transmit power range is QdB greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdB greater than the upper limit of the initial transmit power range, determine, according to at least one of the following formulas, that the number of conduction modules is m times the number of conduction modules corresponding to the initial transmit power range, and the power supply voltage of some basic units in the conduction modules is n times the power supply voltage corresponding to the initial transmit power range, wherein the power supply voltage of the remaining basic units is the power supply voltage corresponding to the initial transmit power range: when the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit, the parameters Q, m, and n satisfy the following formula:

[0148] Q = 10 × lg(n) 2 ), m = 1;

[0149] When a new bit control signal is used to control the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0150] Q = 10 × lg(m), n = 1;

[0151] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the static change of the number of conductions of the transmitting module, the parameters Q, m, and n satisfy the following formula:

[0152] Q = 10 × lg(n) 2 ·m).

[0153] In the above scheme, if the lower limit of the target transmit power range is QdBm greater than the lower limit of the initial transmit power range, and the upper limit of the target transmit power range is QdBm greater than the upper limit of the initial transmit power range, it can be considered that only the window position of the transmit power is adjusted at this time. At this time, by adjusting the number of transmit modules in the digital transmitter and the power supply voltage of the basic unit in the transmit modules, and by using the newly added bit control signal to control the adjustment of the corresponding transmit power window position of the digital transmitter, the static adjustment of the corresponding transmit power window position of the digital transmitter can be achieved, thereby realizing a larger dynamic range of transmit power of the digital transmitter.

[0154] Furthermore, based on the above implementation, if Q = 6, m = 1, and n = 2, then for each basic unit in the conducting transmission module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmission power range, and the supply voltage corresponding to other basic units is twice the supply voltage corresponding to the initial transmission power range; wherein, a new bit control signal is added, which is used to control the static switching of the supply voltage corresponding to the basic unit; or, if Q = 6, m = 2, For each basic unit in the activated transmitter module, the supply voltage corresponding to one basic unit is the supply voltage corresponding to the initial transmit power range, and the supply voltage corresponding to other basic units is [missing value]. The number of bits is increased by 10 times; among them, two new bit control signals are added, one bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit, and the other bit control signal is used to control the static change of the number of conduction bits of the transmitting module.

[0155] Furthermore, based on the above implementation, the determining module 701 is specifically used to: when the lower limit of the target transmission power range is PdB greater than the lower limit of the initial transmission power range, the upper limit of the target transmission power range is QdB greater than the upper limit of the initial transmission power range, and Q>P, determine, according to at least one of the following formulas, that the number of conducting units of the transmission module is m times the number of conducting units corresponding to the initial transmission power range, and the power supply voltage of some basic units in the conducting transmission module is n times the power supply voltage corresponding to the initial transmission power range, wherein the power supply voltage of the remaining basic units is the power supply voltage corresponding to the initial transmission power range; when a new bit control signal is used to control the dynamic switching of the power supply voltage corresponding to the basic unit and the static change of the number of conducting units of the transmission module, the parameters Q, P, m, and n satisfy the following formula:

[0156] Q = 10 × lg(n) 2 ·m), P=10×lg(m);

[0157] When the newly added bit control signal is used to control the static switching of the power supply voltage corresponding to the basic unit and the dynamic change of the number of conduction modules, the parameters Q, P, m, and n satisfy the following formula:

[0158] Q = 10 × lg(n) 2 ·m), P=10×lg(n 2 ).
