Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technology, and in particular to a radio frequency transceiver circuit, method, electronic device, storage medium and chip. Background Art

[0002] With the continuous development of communication technology, the accuracy and capability requirements for wireless communication are also constantly improving. For example, the 3GPP protocol (3rd Generation Partnership Project) requires that during the transmission of RF signals, when the receiving level is equal to -25.7dBm, the receiving bit error rate of the RF signal must be less than 5%. Therefore, in the wireless communication module LTE (Long Term Evolution) standard, in order to improve the receiving sensitivity of the RF signals in the three frequency bands Band38 / 40 / 41, the receiving path of the RF transceiver circuit will basically add an external LNA bypass (low noise amplifier bypass).

[0003] Although the low noise amplifier bypass can improve the RF signal receiving sensitivity of the RF transceiver circuit, when the input level of the RF transceiver circuit is large, the gain of the low noise amplifier bypass to the input level is too large, which will cause the low noise amplifier inside the transceiver (radio transceiver) to saturate prematurely, resulting in the maximum input level of the RF transceiver circuit not meeting the 3GPP protocol specifications. At present, in order to take into account the sensitivity and maximum input level of the RF transceiver circuit, engineers can only add attenuation matching to the back end of the low noise amplifier bypass during the design or debugging process of the low noise amplifier bypass to perform debugging.

[0004] However, the inventors of the present application discovered that, during the implementation of the attenuation matching method, the attenuation matching debugging process requires continuous verification and matching, which is labor-intensive and costly to implement. Furthermore, the sensitivity of the RF transceiver circuit obtained after the attenuation matching debugging cannot be adjusted to the optimal level. Summary of the invention

[0005] The purpose of some embodiments of the present application is to provide a radio frequency transceiver circuit, method, electronic device, storage medium and chip.

[0011] Compared with the prior art, the radio frequency transceiver circuit provided by the embodiment of the present application is provided with a power distribution module, a power detection module and a power amplification module in the process of constructing a low noise amplifier bypass. After the main link receives an external input signal, the power distribution module distributes the power of the input signal to generate a first signal for generating a control signal and a second signal for subsequent radio frequency signal transmission; the power detection module generates a control signal for controlling the processing of the second signal according to the first signal; the power amplification module amplifies the second signal according to the control signal and transmits the amplified second signal to the main link, or directly transmits the second signal to the main link without amplifying the second signal, so that the main link can output the radio frequency signal.

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0024] The implementation details of the camera control method described in this application will be specifically described below in conjunction with specific embodiments. The following content is only the implementation details provided for ease of understanding and is not necessary for implementing this solution.

[0025] The first aspect of the embodiment of the present application provides a radio frequency transceiver circuit. In a specific application, the radio frequency transceiver circuit can be applied to a baseband chip, a radio frequency signal transceiver device, and a terminal device with radio frequency signal transceiver capability, such as a computer, a mobile phone, and other electronic devices. The structural diagram of the radio frequency transceiver circuit can refer to Figure 1 , including: a main link 01 and a low-noise amplifier bypass 02, wherein the low-noise amplifier bypass 02 includes a power distribution module 101, a power detection module 102, and a power amplifier module 103.

[0026] During the process of transmitting and receiving RF signals, the main link 01 receives an input signal transmitted from the outside through an antenna, and then transmits the input signal to the power distribution module 101 in the low noise amplifier bypass 02 after filtering the noise in the input signal through a filter. The input end of the power distribution module 101 is connected to the main link, and the output end is connected to the power detection module 102 and the power amplification module 103 respectively. After receiving the input signal transmitted by the main link, the input signal is power-distributed according to a preset power allocation rule or mechanism, a first signal and a second signal are generated, and the first signal is transmitted to the power detection module 102, and the second signal is transmitted to the power amplification module 103. The output end of the power detection module 102 is connected to the power amplification module 103. After receiving the first signal transmitted by the power distribution module 101, the power amplification module 103 determines whether the second signal needs to be power-amplified according to the power of the first signal, generates a control signal according to the judgment result, and sends the control signal to the power amplification module 103. The output end of the power amplifier module 103 is connected to the main link 01. After receiving the second signal sent by the power allocation module 101 and the control signal sent by the power detection module 102, the second signal is power amplified according to the control signal and the power-amplified second signal is transmitted to the main link 01, or the second signal is not amplified and the second signal is directly transmitted to the main link 01 for the main link 01 to output the RF signal. By adding a power allocation module and a power detection module in the bypass of the low-noise amplifier, and generating a control signal of whether to power amplify the input signal according to the power of the input signal by the power detection module, the power amplifier module is controlled to selectively access the low-noise amplifier to power amplify the input level, so as to achieve the problem of not meeting the 3GPP protocol specification for the maximum input level of the radio transceiver due to the introduction of the bypass while taking into account the signal receiving sensitivity of the RF transceiver circuit.

[0027] Furthermore, the power detection module is specifically used to obtain the power size of the input signal according to the first signal, and detect whether the power size of the input signal is greater than a preset threshold value; when the power size of the input signal is greater than the preset threshold value, a first control signal is output, and the first control signal is used to control the power amplification module to amplify the second signal and transmit the amplified second signal to the main link; when the power size of the input signal is not greater than the preset threshold value, a second control signal is output, and the first control signal is used to control the power amplification module to directly transmit the second signal to the main link.

[0028] Specifically, when the power of the input signal is low or at a low level, the input signal needs to be amplified to ensure the signal receiving sensitivity of the RF transceiver circuit. When the power of the input signal is high or at a high level, it is necessary to avoid the problem that the maximum input level does not meet the 3GPP protocol specification due to the bypass of the low noise amplifier. Therefore, in the process of designing or debugging the RF transceiver circuit, a preset threshold is set for the power of the input signal according to the application scenario of the RF transceiver circuit in advance. In the process of acquiring the first signal and generating a control signal according to the first signal, the power detection module calculates the power of the input signal according to the first signal, and then detects whether the power of the input signal is greater than the preset threshold. When the power of the input signal is greater than the preset threshold, the first control signal for controlling the power amplifier module to access the low noise power amplifier to amplify the second signal is output; when the power of the input signal is not greater than the preset threshold, the second control signal for controlling the power amplifier module to skip the low noise amplifier and directly transmit the second signal to the main link is output. By judging whether the input signal level is high based on the relationship between the input signal power and the preset threshold, the low-noise power amplifier bypass is selectively opened to gain the input according to the power of the input signal, thereby ensuring the signal reception sensitivity while avoiding the maximum input level not meeting the 3GPP protocol specifications.

[0029] Furthermore, the value range of the preset threshold includes -85dBm to -40dBm, for example, -75dBm, -60dBm, -50dBm, etc. Taking the preset threshold as -50dBm as an example, when the power of the input signal calculated according to the first signal is greater than -50dBm, the power detection module determines that the input signal is a high-level signal, and outputs a second control signal to control the power amplifier module to directly transmit the second signal to the main link; when the power of the input signal calculated according to the first signal is not greater than -50dBm, the power detection module determines that the input signal is a low-level signal, and outputs a first control signal to control the power amplifier module to transmit the second signal to the low-noise power amplifier for gain, and then transmits the amplified second signal to the main link. By setting an appropriate preset threshold, it is convenient to accurately selectively access the low-noise amplifier circuit according to the power size of the input signal.

[0030] In one example, a power amplification module includes: a first selection unit, a second selection unit and a first amplification unit; the input end of the first selection unit is respectively connected to the power distribution module and the power detection module, and the output end is connected to the second selection unit and the first amplification unit, and is used to transmit the second signal to the first amplification unit or the second selection unit according to the control signal; the input end of the second selection unit is respectively connected to the power detection module, the first selection unit and the first amplification unit, and the output end is connected to the main link, and is used to transmit the signal output by the first selection unit or the first amplification unit to the main link according to the control signal; the first amplification unit is used to amplify the second signal and transmit the amplified second signal to the second selection unit.

[0031] Specifically, the structural diagram of the RF transceiver circuit can be referred to Figure 2 , the main link is composed of an antenna, a SAW filter, a power amplifier and a radio transceiver. The antenna is used to receive external radio frequency signals and transmit the radio frequency signals generated by the main link; the SAW filter is used to filter out noise from the radio frequency signals from the outside and the power amplifier by converting the received signal into mechanical energy and then converting the mechanical energy into radio frequency signals again; the power amplifier is used to perform power gain on the signal generated by the radio transceiver to generate the radio frequency signal to be sent, and transmit the received input signal to the low noise amplifier bypass through a switch; the radio transceiver is used to receive the input signal through the low noise amplifier bypass, and generate the baseband signal of the radio frequency signal to be sent according to the input signal. The low noise amplifier bypass power distribution module, the power detection module and the power amplifier module composed of the first selection unit, the second selection unit and the first amplification unit are composed. The output end of the power amplifier unit is connected to the radio transceiver in the main link, and is used to provide the radio transceiver with an input signal to generate the baseband signal of the radio frequency signal to be sent.

[0032] During the process of transmitting and receiving RF signals, after receiving the externally transmitted input signal through the antenna, the SAW filter filters the signal for noise removal, and then the power amplifier transmits the input signal to the power distribution module in the bypass of the low-noise power amplifier, such as a coupler, through the switch. Then the power distribution module distributes the power of the input signal, generates a first signal and a second signal, and transmits them to the power detection module and the first selection unit respectively. The power detection module generates a control signal for controlling the connection path between the first selection unit and the second selection unit according to the first signal, and sends the control signal to the first selection unit and the second selection unit. When the second signal needs to be amplified, the power detection unit outputs a control signal to control the first selection unit and the second selection unit to conduct the path containing the low-noise amplifier, so as to send the second signal amplified by the first amplification unit to the main link; when the second signal does not need to be amplified, the power detection unit outputs a control signal to control the first selection unit and the second selection unit to conduct the path that does not contain the low-noise amplifier, and directly transmit the second signal to the main link. Two paths including a power amplifier and not including a power amplifier are constructed through two selection units. One path is selectively connected according to a control signal to process and transmit the second signal, thereby accurately realizing the selective access of the low-noise power amplifier bypass.

[0033] In another example, a power amplification module includes: a third selection unit and a second amplification unit; the input end of the third selection unit is respectively connected to the power distribution module and the power detection module, and the output end is connected to the main link and the second amplification unit, and is used to transmit the second signal to the power amplification unit or the main link according to the control signal; the output end of the second amplification unit is connected to the main link, and is used to process the second signal and transmit the amplified second signal to the main link.

[0034] Specifically, the power amplification module can also be composed of a third selection unit and a second amplification unit, the input end of the third selection unit is connected to the power distribution module and the power detection module, and the output end is respectively connected to the second amplification unit and the radio transceiver of the main link. After the power distribution unit obtains the input signal, it transmits the first signal generated after power distribution to the power detection module, and transmits the generated second signal to the third selection unit. In the case where the second signal needs to be amplified, the power detection unit outputs a control signal to control the third selection unit to turn on the path containing the low-noise amplifier, and transmit the second signal amplified by the second amplification unit to the main link; in the case where the second signal does not need to be amplified, the power detection unit outputs a control signal to control the third selection unit to turn on the path that does not contain the low-noise amplifier, and directly transmits the second signal to the main link. Directly using a selection unit and an amplification unit to form a power amplification module can reduce the difficulty and cost of implementation while being able to accurately achieve selective access to the amplifier for signal gain.

[0035] It is worth mentioning that the above-mentioned first selection unit, second selection unit and third selection unit can be electronic devices with selective conduction capability such as single-pole double-throw switches, IGBT tubes or MOS tubes. This embodiment does not limit the specific type of electronic devices used by the selection units.

[0036] In another example, the power amplification module includes several power amplification units, the output of the preceding power amplification unit is connected to the input of the succeeding power amplification unit, and the output of the last power amplification unit is connected to the main link; the output of the power detection module is respectively connected to each power amplification unit, and is also used to generate a target control signal for each power amplification unit according to a target amplification gain, and transmit each target control signal to each corresponding power amplification unit; the power amplification unit is used to amplify the input signal according to the target control signal and transmit the amplified input signal to the next stage, or directly transmit the input signal to the next stage.

[0037] Specifically, the structural diagram of the power amplifier module can be referred to Figure 3 For the sake of convenience, here we take the example of a power amplifier module including power amplifier unit 1, power amplifier unit 2 and power amplifier unit 3 with gains of XdB, YdB and ZdB respectively, and the control signal output by the power detection module takes the general-purpose input / output level (GIPO) as an example. Power amplifier unit 3 is used as the first stage, power amplifier unit 1 is used as the third stage, the output of the previous stage is used as the input of the next stage, and the output of power amplifier unit 3 is connected to the main link. The control signal of 0 indicates access gain, and the control signal of 1 indicates no access gain. According to the connection characteristics of the circuit, the gain that the power amplifier module can add to the second signal can refer to

[0038] Table 1:

[0039]

[0040] Table 1

[0041] During the process of transmitting and receiving radio frequency signals, the power detection module can first determine whether the second signal needs to be gained according to the first signal. If the second signal needs to be gained, the power detection module can also determine the target amplification gain of the second signal according to the user input instruction or the preset program according to the current actual application scenario. Then, according to the target amplification gain, the state of each power amplification unit in the process of gaining the second signal is determined to obtain the matching of the power amplification unit in the process of amplifying the second signal. Then, a target control signal is generated for each power amplification unit, and the target control signal is transmitted to each power amplification unit, so that each power amplification unit gains the input signal according to the control signal or directly transmits it to the next level. For example, if the required gain is (X+Z)dB, the control signal output by the power detection module is GPIO_0=0; GPIO_1=1; GPIO_2=0. By setting a plurality of power amplification units in series, and generating a target control signal for each amplification unit according to the target gain to control whether each amplification unit gains the input signal, the flexible adjustment of the bypass gain of the low noise amplifier is accurately and efficiently realized.

[0042] It should be noted that the above examples in this embodiment are illustrative for easy understanding and do not limit the technical solution of the present invention. The steps of the above methods are divided only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications or introducing insignificant designs to the algorithm or process, but not changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0047] Specifically, after the first signal is generated, it is determined whether the second signal needs to be amplified based on the first signal, and a control signal for controlling the processing of the second signal is generated based on the determination result.

[0048] Step 403: selectively amplify the second signal according to the control signal to obtain a target input signal.
