Description

Technical Field

[0001] The present application relates to the technical field of multi-mode power amplifiers, and in particular to a method, device, storage medium and electronic device for processing radio frequency signals. Background Art

[0002] As products enter the stock market, cost reduction becomes an important task for hardware development. In addition to choosing the stable performance Qualcomm and MTK (MediaTek) platforms, we are also actively exploring domestic platforms. Although domestic platforms have cost advantages, they also face some challenges, such as insufficient output capacity of WTR (Wireless Transceiver) and crystal frequency multiplication interference. Taking low frequency as an example, the existing technical solution adds a single-pole double-throw switch (SPDT) to the input of the multi-mode power amplifier (MMPA). The output of the RF chip is divided into two paths through the SPDT and enters the low gain (LB) or high gain (HB) input port of the multi-mode power amplifier (MMPA). The high-gain mode uses a matching direct-pass circuit, while in the low-gain mode, it switches to the path of the attenuation network, artificially increasing the attenuation to reduce the gain of the power amplifier in the low-gain mode in disguise, thereby effectively reducing interference and solving the problem of demodulation failure caused by interference to the minimum power. Although this solution can solve some problems, it still has the following defects: Increased material cost and PCB (Printed Circuit Board) area: The added single-pole double-throw switch hardware circuit leads to increased material cost, and also takes up additional PCB space, affecting the compactness of the overall design. Restrictions on power amplifier selection: This solution requires the selection of a power amplifier with two input ports, which limits the flexibility in power amplifier selection and may reduce the range of optional equipment. Increased link insertion loss: The low-frequency band (frequency range) also needs to pass through a single-pole double-throw switch in high-gain mode, which not only increases the link insertion loss, but may also affect the RF performance and reduce the overall performance of the system. Overall, although the existing solutions have alleviated the interference problem to a certain extent, they will bring additional costs and performance impacts. Summary of the invention

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0024] According to a first aspect of an embodiment of the present application, a method for processing a radio frequency signal is provided, which is applied to a multi-mode power amplifier. Optionally, as follows: Figure 1 As shown, the above method includes:

[0025] S102, when receiving a first radio frequency signal transmitted by the radio frequency transceiver, determining a target frequency band and a target gain mode corresponding to the first radio frequency signal, wherein the gain mode includes a low gain mode and a high gain mode;

[0026] S104, obtaining calibration information of a target frequency band of the multi-mode power amplifier from a calibration file, and obtaining logic information of a target gain mode of the target frequency band of the multi-mode power amplifier from a driver file, wherein, when the target gain mode is a low gain mode and the low gain mode of the target frequency band of the multi-mode power amplifier is interfered, the logic information is a low gain mode of an adjacent frequency band of the target frequency band;

[0027] S106, coupling and amplifying the first radio frequency signal according to the calibration information and the logic information to obtain a coupled and amplified second radio frequency signal;

[0028] S108: Send the second radio frequency signal to the antenna through the output port corresponding to the logic information.

[0029] Optionally, in this embodiment, a multi-mode power amplifier (MMPA Multi-Mode Power Amplifier) ​​is a power amplifier used to support multiple communication modes (such as 2G, 3G, 4G, and even 5G), which is usually used in the RF front end of mobile devices. It can flexibly adjust the working mode according to different communication standards (such as LTE, WCDMA, GSM, etc.) to meet the requirements of different frequency bands and modulation methods. The interference can be crystal frequency multiplication interference, which refers to the interference signal generated by the frequency multiplication phenomenon when the crystal oscillator used in the electronic device is working. Crystal frequency multiplication is the higher harmonics of the fundamental frequency signal generated by the crystal oscillator. The frequencies of these higher harmonics are integer multiples of the fundamental frequency, which may interfere with other signals in the electronic circuit, thereby causing performance problems or misoperation.

[0030] Optionally, in this embodiment, after the multi-mode power amplifier receives a low-level first RF signal from the RF transceiver, it first determines the target frequency band and operating mode corresponding to the RF signal, and then obtains the calibration information of the target frequency band from the calibration file, and obtains the logic information of the target operating mode from the driver file. If the target operating mode is a low-gain mode, but is interfered by the crystal frequency doubling, the logic information will point to the low-gain mode of the adjacent frequency band. This switching mechanism can be dynamically adjusted to cope with different working environments. Based on the obtained calibration information and logic information, coupling and amplification processing is performed on the low-level RF signal, including signal matching, amplification and filtering, etc., so as to upgrade the low-level RF signal to a high-level RF signal. Finally, the obtained high-level second RF signal is sent to the antenna through the output port corresponding to the logic information.

[0031] Optionally, in this embodiment, for example, when the target frequency band is Band 5, the target working mode is the low-gain mode, and the low-gain mode of the multi-mode power amplifier Band 5 cannot work normally due to the interference of the crystal frequency doubling, by modifying the configuration of the low-gain mode of Band 5 to the low-gain mode configuration of its adjacent frequency band Band 8, the multi-mode power amplifier can continue to work normally by using its multi-port and multi-band characteristics, and finally the RF signal will be output through the port of Band 8. The multi-mode power amplifier usually has multiple output ports, each port supports a different frequency band, and there is a certain degree of isolation between these ports, usually about 20 dB, which means that when a certain frequency band cannot work normally, the RF signal of the adjacent frequency band can provide certain power support through coupling to reduce signal loss. Therefore, since the output ports used by Band 5 and Band 8 are adjacent, and the isolation between the output ports is about 20 dB, this physical characteristic enables the signal of Band 8 to provide a certain low-power signal for Band 5 through coupling. By configuring the low-gain logic of Band 5 to the low-gain configuration of Band 8, the signal of Band 8 is actually used to couple the adjacent ports of the multi-mode power amplifier to provide low-power transmission of Band 5. The complexity of adding an additional attenuation network (such as a 2T switch to distinguish between high and low gains) in the traditional solution is avoided, and the isolation of adjacent frequency bands is used. The actual effect is similar to adding 20dB of attenuation to Band 5.

[0032] Optionally, in this embodiment, by switching to a low-gain mode of an adjacent frequency band when the low-gain mode is interfered by the crystal frequency doubling, interference can be effectively reduced and signal availability can be improved. In addition, the reliance on expensive high-gain amplifiers can be reduced, thereby reducing hardware costs while ensuring communication quality. The multi-mode power amplifier not only improves performance, but also improves the reliability and efficiency of communication in complex wireless environments.

[0033] As an optional example, before determining the target frequency band and the target gain mode corresponding to the first radio frequency signal, the method further includes:

[0034] In the case where it is detected that the low gain mode of the first frequency band is interfered, the logic information of the low gain mode of the first frequency band in the driving file is modified to the low gain mode of the second frequency band, wherein the first frequency band is any frequency band of the multi-mode power amplifier, the second frequency band is an adjacent frequency band of the first frequency band, and the difference between the minimum frequencies of the first frequency band and the second frequency band is less than the target threshold;

[0035] According to the logic information of the low gain mode of the first frequency band, the switching point of the low gain mode of the first frequency band, the output power of the first frequency band, and the adaptive power tracking voltage corresponding to the first frequency band in the calibration file are adjusted.

[0036] Optionally, in this embodiment, when it is detected that the low gain mode of a certain frequency band of the multi-mode power amplifier is interfered, the logic information of the low gain mode of the frequency band in the driving file is modified to the low gain mode of its adjacent frequency band, and the minimum frequency difference between the frequency band and its adjacent frequency band is less than the target threshold. According to the new logic information, the switching point, output power and corresponding adaptive power tracking voltage (APT voltage) of the low gain mode of the frequency band in the calibration file are adjusted to ensure the normal operation and performance optimization of the multi-mode power amplifier under the new setting. For example, it is detected that the low gain mode of Band 5 of the multi-mode power amplifier is interfered. In this case, the logic information of the low gain mode of Band 5 in the driving file will be modified to the low gain mode of Band 8 (the adjacent frequency band of Band 5). Here, the minimum frequency difference between Band 5 and Band 8 is less than the target threshold to ensure that they are close enough in the spectrum to facilitate switching and coupling. In order to ensure the normal operation of Band 5, the following parameters in the calibration file also need to be adjusted: Switching point: According to the new logic setting, the switching point of the low gain mode of Band 5 is adjusted to adapt to the new working conditions. Output power: Adjust the output power of Band 5 according to the signal requirements to ensure that the signal can reach the required strength when transmitting. Adaptive power tracking voltage (APT voltage): Modify the APT voltage corresponding to Band 5 to ensure that power tracking can work properly under the new configuration.

[0037] As an optional example, according to the calibration information and the logic information, coupling and amplifying the first radio frequency signal to obtain the coupled and amplified second radio frequency signal includes:

[0038] When the target gain mode is a low gain mode and the low gain mode of the target frequency band of the multi-mode power amplifier is interfered with, the first RF signal is coupled and amplified through the low gain mode of the adjacent frequency band according to the low gain mode switching point of the target frequency band, the output power of the target frequency band and the adaptive power tracking voltage corresponding to the target frequency band in the calibration information to obtain a second RF signal.

[0039] Optionally, in this embodiment, when the target working mode is a low-gain mode and the low-gain mode of the target frequency band of the multi-mode power amplifier is interfered, the low-gain mode switching point, output power and corresponding adaptive power tracking voltage (APT voltage) of the target frequency band are extracted according to the calibration information, and the low-gain mode of the adjacent frequency band is used, combined with the above information, to couple and amplify the low-level RF signal, ensuring that the signal can reduce interference while maintaining appropriate gain, and finally amplify the low-level first RF signal into a high-level second RF signal. The performance of the multi-mode power amplifier under interference conditions is effectively improved, and the availability and stability of the signal are ensured. For example, if the target frequency band is Band 5, the low-gain mode switching point, output power and corresponding adaptive power tracking voltage (APT voltage) of Band 5 are extracted according to the calibration information, and Band 8 is selected as the adjacent frequency band to use its low-gain mode for signal processing. The low-level first RF signal is coupled and amplified through the low-gain mode of Band 8. According to the switching point and output power of Band 5, the processing logic is adjusted to ensure that the signal amplification meets the expected performance. Through the above steps, the low-level Band 5 RF signal is successfully amplified into a high-level second RF signal.

[0040] As an optional example, according to the calibration information and the logic information, coupling and amplifying the first radio frequency signal to obtain the coupled and amplified second radio frequency signal includes:

[0041] When the gain mode of the target frequency band of the multi-mode power amplifier is not disturbed, the first RF signal is coupled and amplified through the target gain mode of the target frequency band according to the target gain mode switching point of the target frequency band, the output power of the target frequency band and the adaptive power tracking voltage corresponding to the target frequency band in the calibration information to obtain the second RF signal.

[0042] Optionally, in this embodiment, if the operating modes of the target frequency bands of the multi-mode power amplifier are not disturbed, the target operating mode switching point, output power and corresponding adaptive power tracking voltage (APT voltage) of Band 5 are extracted from the calibration information, and the received low-level RF signal is coupled and amplified according to the setting of the target operating mode. Specifically, the target operating mode of Band 5 is used to process the signal to ensure that the signal meets expectations in terms of gain setting and performance. Through the above processing, the low-level first RF signal is successfully amplified into a high-level second RF signal, ready to be sent to the antenna. It is ensured that under normal working conditions, the amplification and output of the RF signal achieve optimal performance, thereby improving the reliability and quality of communication.

[0043] As an optional example, sending the second radio frequency signal to the antenna through the output port corresponding to the logic information includes:

[0044] When the target gain mode is the low gain mode and the low gain mode of the target frequency band of the multi-mode power amplifier is interfered, the second radio frequency signal is sent to the antenna through an output port of a frequency band adjacent to the target frequency band.

[0045] Optionally, in this embodiment, when the target operating mode is the low-gain mode, if it is detected that the low-gain mode of the target frequency band (such as Band 5) of the multi-mode power amplifier is interfered, based on the previous logic information, the output port of the adjacent frequency band (such as Band 8) is selected as a substitute to ensure the stability of signal transmission, and the coupled and amplified high-level RF signal is sent to the antenna through the output port of Band 8. This switching ensures that even if Band 5 is interfered, the signal can still be effectively transmitted, and the communication quality can be maintained under interference conditions, ensuring that the signal is smoothly transmitted to the antenna, thereby improving the reliability and performance of the overall system.

[0046] As an optional example, sending the second radio frequency signal to the antenna through the output port corresponding to the logic information includes:

[0047] In the case that the gain modes of the target frequency band of the multi-mode power amplifier are not interfered, the second radio frequency signal is sent to the antenna through the output port of the target frequency band.

[0048] Optionally, in this embodiment, when the operating mode of the target frequency band of the multi-mode power amplifier is not interfered, the system determines that the frequency band can be used for signal transmission, and directly sends the coupled and amplified high-level second RF signal to the antenna through the output port of the frequency band, thereby ensuring that the signal is transmitted smoothly without interference, ensuring the reliability and effectiveness of signal transmission, and improving the overall communication quality.

[0049] In conjunction with an example, the present application relates to a method for processing radio frequency signals, which is applied to a multi-mode power amplifier, in order to reduce the power of the multi-mode power amplifier in a low gain mode, thereby reducing crystal frequency multiplication interference. Figure 2The schematic diagram of the multi-mode power amplifier shown in FIG. takes low-frequency Band 5 as an example, and uses the low-gain configuration of the adjacent ports of the multi-mode power amplifier to achieve the goal. The adjacent output ports of the multi-mode power amplifier have an isolation of about 20dB, which can effectively reduce the interference in the low-gain mode. Specifically, Band 5 (low frequency) can be combined with any adjacent low frequency band (such as Band 8, Band 20, Band 28, etc.) because the low frequency, intermediate frequency and high frequency inside the multi-mode power amplifier use different amplification groups. When the minimum power of Band 5 is interfered by the crystal frequency doubling and cannot be demodulated, the low gain logic of Band 5 can be configured to be the same as Band 8. The energy coupled through the adjacent port (about 20dB isolation) can be used as a low-power transmission of Band 5, which is equivalent to achieving 20dB attenuation. This method replaces the traditional attenuation matching scheme and 2T switch configuration, and simplifies the switching of high and low gains. To ensure the effectiveness of the solution, the driver file and calibration file need to be modified. The logic configuration table in the driver file should make the low-gain switch logic of Band 5 consistent with Band 8. At the same time, the low-gain adaptive power tracking voltage setting of Band 5 in the calibration file also needs to be adjusted to adapt to the new logic configuration. These modifications will affect the low-gain saturation power of Band 5, so the low-gain switching point, power and adaptive power tracking voltage need to be adjusted accordingly during calibration. This method is not only applicable to low-frequency bands, but also to medium and high-frequency bands to solve the minimum power demodulation problem caused by crystal frequency doubling. At the same time, the layout of the printed circuit board of the multi-mode power amplifier also needs to be adapted and adjusted, and the switch ports and lines of adjacent ports need to be compact, such as Band 5 and Band 8. This method achieves the effect of attenuating interference by coupling, which saves both cost and printed circuit board space.
