Summary of the Invention

[0036] Example 1

[0037] Figure 1This is a schematic diagram of a transmit path power amplifier control system according to Embodiment 1 of the present invention. This transmit path power amplifier control system is applicable to situations where the operating state of a power amplifier needs to be controlled. The transmit path power amplifier control system can be implemented using both software and hardware, and may include a power amplifier control device to control the operating state of the power amplifier.

[0038] like Figure 1 As shown, the first embodiment of the present invention provides a power amplifier control system for a transmission path, including: a power amplifier control device 110 and a power amplifier 120, wherein the power amplifier control device 110 is connected to the power amplifier 120.

[0039] The power amplifier control device 110 is used to monitor the enable signal of the power amplifier 120 and the coupling signal of the power amplifier signal. When the enable signal and the coupling signal are detected to meet the preset conditions, the device sends a control command to the power amplifier 120.

[0040] The power amplifier 120 is used to amplify the acquired power amplifier signal after receiving the control command, and output the amplified power amplifier signal.

[0041] In this context, the power amplifier control device 110 can be understood as the control device for the power amplifier. The power amplifier control device 110 can be an electronic device with transceiver functions. No specific restrictions are placed on the model of the power amplifier control device 110 here.

[0042] In this embodiment, the power amplifier control device 110 is used to monitor the enable signal and the coupling signal of the power amplifier signal in real time. Control commands are only sent when both the enable signal and the coupling signal are detected, thus delaying the time it takes for the power amplifier 120 to enter the working state. The enable signal can be transmitted by the transmission path control unit within the RF link of the BeiDou short message transmission path; the source of the coupling signal is not specifically limited here.

[0043] In this embodiment, the power amplifier control device 110 is connected to the power amplifier 120 and is used to control the power amplifier 120 to enter the working state by sending control commands.

[0044] Among them, the power amplifier 120 is referred to as the power amplifier, which can amplify the power of the signal.

[0045] In this embodiment, the power amplifier 120 is connected to the power amplifier control device 110 and can receive control commands sent by the power amplifier control device 110. After receiving the control command, the power amplifier 120 enters the working state, amplifies the acquired power amplifier signal, and outputs the amplified power amplifier signal. The power amplifier 120 can obtain the power amplifier signal from the filter. The process of how the power amplifier 120 amplifies the power amplifier signal is not described in detail here.

[0046] Embodiment 1 of this invention provides a power amplifier control system for a transmitting path. First, a power amplifier control device monitors the enable signal and the coupling signal of the power amplifier. When the enable signal and the coupling signal meet preset conditions, a control command is sent to the power amplifier. Then, upon receiving the control command, the power amplifier amplifies the acquired power amplifier signal and outputs the amplified signal. By simultaneously monitoring the enable signal and the coupling signal, this system can accurately determine the time when the power amplifier enters the working state, avoiding increased power consumption caused by prematurely turning on the power amplifier. Furthermore, this system eliminates the need to control the power amplifier's power supply switching; instead, it controls the power amplifier to enter the working state via control commands, thus solving the problem of reduced power amplifier lifespan caused by prolonged switching of the power amplifier's power supply in existing technologies.

[0047] Furthermore, the power amplifier control device 110 is specifically used to: send a control command to the power amplifier 120 when the coupling signal is detected again within a preset time after the enable signal is detected.

[0048] When the transmission path control unit within the RF link of the BeiDou short message transmission path transmits an enable signal to the outside of the chip, the transmission path control unit within the RF link of the BeiDou short message transmission path has not yet started transmitting the BeiDou signal, i.e., the power amplifier signal. If the power amplifier control device 110 turns on the power amplifier 120 as soon as it detects the enable signal, the power amplifier will turn on prematurely, increasing power consumption. Therefore, the power amplifier 120 should not be turned on during the period between transmitting the enable signal and transmitting the power amplifier signal. Thus, the power amplifier control device 110 needs to detect the coupling signal before sending a control command to turn on the power amplifier 120. It is understandable that the power amplifier control device 110 detects the coupling signal later than it detects the enable signal; that is, the power amplifier control device 110 detects the enable signal first and then the coupling signal a certain period later. This creates a transmission delay, thus delaying the power amplifier 120 from entering the working state and reducing power consumption.

[0049] It should be noted that if the power amplifier control device 110 does not detect a coupling signal within a preset time after detecting the enable signal, it will not send a control command to the power amplifier 120.

[0050] Furthermore, before receiving the control command or after executing the control command, the power supply terminal of the power amplifier 120 is in a high-impedance state.

[0051] In this configuration, when the power amplifier 120 does not receive a control command from the power amplifier control device 110, its power supply terminal remains in a high-impedance state to reduce the power consumption of the power amplifier; after the power amplifier 120 outputs the amplified power amplifier signal, its power supply terminal remains in a high-impedance state until it receives a control command again.

[0052] Example 2

[0053] Figure 2 This is a schematic diagram of a power amplifier control system for a transmitting path according to Embodiment 2 of the present invention. Embodiment 2 is an optimization based on the above embodiments. For details not covered in this embodiment, please refer to Embodiment 1, which will not be elaborated here.

[0054] In this embodiment, the transmit path power amplifier control system further includes a coupler 130, which is connected to the power amplifier control device 110;

[0055] Coupler 130 is used to couple the power amplifier signal to obtain a coupled signal, and send the coupled signal to the power amplifier control device 110.

[0056] Coupler 130 can be a device for coupling signals. The model and type of coupler 130 are not specifically limited here, but a low-power and small-sized coupler is preferred.

[0057] In this embodiment, coupler 130 is used to receive the power amplifier signal sent by the BeiDou short message transmission channel and couple the power amplifier signal to obtain a coupling signal. Coupler 130 is connected to power amplifier control device 110 and is used to send the generated coupling signal to power amplifier control device 110 so that power amplifier control device 110 can monitor the coupling signal.

[0058] The second embodiment of the present invention provides a power amplifier control system for a transmission path, which utilizes a coupler in the system to generate a coupling signal.

[0059] Example 3

[0060] Figure 3This is a flowchart illustrating a control method for a transmit path power amplifier according to Embodiment 3 of the present invention. Embodiment 14 is applicable to controlling the operating state of a power amplifier. This method can be executed by the power amplifier control device in the transmit path power amplifier control system provided in Embodiment 1 of the present invention. The power amplifier control device can be implemented using hardware and software. The method specifically includes the following steps:

[0061] Step 110: Monitor the enable signal of the power amplifier and the coupling signal of the power amplifier signal.

[0062] The method by which the power amplifier control device monitors the enable signal and the coupling signal is not limited. One feasible method is as follows: when the power amplifier control device receives an enable signal, it indicates that the power amplifier control device has detected the enable signal; when the power amplifier control device receives a coupling signal, it indicates that the power amplifier control device has detected the coupling signal.

[0063] The source of the coupling signal is not specifically limited. The enable signal can be transmitted by the transmission path control unit within the radio frequency link of the BeiDou short message transmission path.

[0064] Step 120: When the enable signal and coupling signal of the power amplifier are detected to meet the preset conditions, a control command is sent to the power amplifier to control the operation of the power amplifier.

[0065] In order to avoid the power amplifier control device sending a control command to put the power amplifier into working state when it detects the enable signal, a coupling signal can be set. The control command to put the power amplifier into working state is sent only when the enable signal is detected and then the coupling signal is detected, thereby delaying the time when the power amplifier 120 enters working state.

[0066] Embodiment 3 of this invention provides a control method for a power amplifier in a transmitting path. First, the enable signal and coupling signal of the power amplifier are monitored. Then, when the enable signal and coupling signal meet preset conditions, a control command is sent to the power amplifier to control its operation. This method can accurately determine the time when the power amplifier enters the working state, avoiding increased power consumption caused by prematurely turning on the power amplifier. This method eliminates the need to control the power amplifier's power supply switching; instead, it controls the power amplifier to enter the working state via a control command, thus solving the problem of reduced power amplifier lifespan caused by prolonged switching of the power amplifier's power supply in existing technologies.

[0067] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0068] Furthermore, the preset condition includes: detecting the coupling signal again within a preset time after the enable signal is detected.

[0069] In the BeiDou short message transmission path, when the transmission path control unit within the RF link transmits an enable signal to the outside of the chip, the transmission path control unit within the RF link has not yet started transmitting the BeiDou signal (i.e., the power amplifier signal). If the power amplifier control device turns on the power amplifier as soon as it detects the enable signal, it will cause the power amplifier to turn on prematurely, increasing power consumption. Therefore, the power amplifier should not be turned on during the period between transmitting the enable signal and transmitting the power amplifier signal. Instead, the power amplifier control device should only send a control command to turn on the power amplifier after detecting the coupling signal. It is understandable that the power amplifier control device detects the coupling signal later than it detects the enable signal; that is, it detects the coupling signal some time after detecting the enable signal. This creates a transmission delay, thus delaying the power amplifier's entry into the working state and reducing power consumption.

[0070] It should be noted that if the power amplifier control device does not detect a coupling signal within a preset time after detecting the enable signal, it will not send a control command to the power amplifier.

[0071] Furthermore, the coupling signal is obtained by coupling the power amplifier signal.

[0072] The coupling signal is obtained by coupling the power amplifier signal with a coupler. The specific coupling process will not be described in detail here.

[0073] Furthermore, before receiving the control command or after executing the control command, the power amplifier's power supply terminal is in a high-impedance state.

[0074] In this system, when the power amplifier does not receive a control command from the power amplifier control device, its power supply terminal remains in a high-impedance state to reduce the power consumption of the power amplifier; after the power amplifier outputs the amplified power amplifier signal, its power supply terminal remains in a high-impedance state until it receives a control command again.

[0075] Example 4

[0076] Figure 4 This is a schematic diagram of a control device for a power amplifier in a transmission path according to Embodiment 4 of the present invention. The device is applicable to controlling the operating state of a power amplifier. The device can be implemented by software and / or hardware and is generally integrated into the power amplifier control equipment.

[0077] like Figure 4 As shown, the device includes a monitoring module 110 and a transmitting module 120.

[0078] The monitoring module 110 is used to monitor the enable signal of the power amplifier and the coupling signal of the power amplifier signal;

[0079] The transmitting module 120 is used to send a control command to the power amplifier when the enable signal and coupling signal of the power amplifier meet the preset conditions, so as to control the operation of the power amplifier.

[0080] In this embodiment, the device first monitors the enable signal of the power amplifier and the coupling signal of the power amplifier signal through the monitoring module 110; then, the sending module 120 sends a control command to the power amplifier when the enabled signal and the coupling signal of the power amplifier meet the preset conditions, so as to control the power amplifier to work.

[0081] This embodiment provides a control device for a power amplifier in a transmission path. This device can avoid increased power consumption caused by prematurely turning on the power amplifier. This device does not require controlling the power amplifier's power supply to turn on or off. Instead, it controls the power amplifier to enter the working state through control commands, which can solve the problem of reduced power amplifier lifespan caused by long-term switching of the power amplifier's power supply in the prior art.

[0082] Furthermore, the preset condition includes: detecting the coupling signal again within a preset time after the enable signal is detected.

[0083] Furthermore, the coupling signal is obtained by coupling the power amplifier signal.

[0084] Furthermore, before receiving the control command or after executing the control command, the power amplifier's power supply terminal is in a high-impedance state.
