Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1 - Figure 7 As shown: A frequency-adjustable radio frequency amplifier, comprising:

[0037] An input terminal 2, which is installed at the side shell of the device body 1 and is used to receive input from an external signal source;

[0038] An input matching adjustment component 8, which is installed at the inner bottom of the operating housing 3, and is used to dynamically adjust the impedance of the input signal and the input impedance of the amplifier to achieve lossless transmission of the signal;

[0039] The photon frequency adjustment component 9 is installed on the inner bottom side of the operating housing 3 and forms a signal matching connection with the input matching adjustment component 8, and is used to realize the selective adjustment of the optical signal frequency by dynamically changing the photon reflection spectrum to form a feedback output of the radio frequency signal;

[0040] A coupling control component 10, which is installed inside the device body 1 and forms a signal connection with the photon frequency adjustment component 9, and is used to assist in fine dynamic adjustment of the photon frequency adjustment component 9 during operation;

[0041] The load RF output matching terminal 7 is mounted on the front end surface of the device body 1 and forms a signal connection with the coupling regulation component 10, and is used to convert the photon signal into an adjusted amplified and filtered RF signal.

[0042] In the present invention, according to Figure 2 , Figure 3 and Figure 5 As shown, the photon frequency adjustment component 9 includes:

[0043] A computing circuit board, an input RF signal conversion connection terminal 901, an optical filter 902, a microring resonator 906 and an acousto-optic modulator 905, a fiber coupler 903 is connected to the side end of the input RF signal conversion connection terminal 901, a side end of the fiber coupler 903 and the optical filter 902 are connected, the fiber coupler 903 is used to couple the input RF-converted optical signal into the optical filter 902 according to a certain proportion, a photoelectric sensor is installed on the side end surface of the fiber coupler 903, the microring resonator 906 and the acousto-optic modulator 905 are arranged in multiple groups, the multiple groups of microring resonators 906 are located inside the acousto-optic modulator 905, and cooperate with the acousto-optic modulator 905 to adjust the optical signal coupled in the optical filter 902.

[0044] A variable capacitor array structure 904 is symmetrically installed at the left and right ends of the fiber coupler 903. The variable capacitor array structure 904 is used to form a signal connection with the photoelectric sensor, and the variable capacitor array structure 904 is electrically connected with the fiber coupler 903, the microring resonator 906 and the acousto-optic modulator 905 in turn.

[0045] The prediction data acquisition microprocessor 907 is installed on the surface of the computing circuit board. The prediction data acquisition microprocessor 907 is electrically connected to the acousto-optic modulator 905 through a feedback line. The side end of the prediction data acquisition microprocessor 907 is installed with a frequency modulation output multi-channel 908.

[0046] In a specific solution, the external RF signal first enters the input RF signal conversion connection terminal 901, where the RF signal is converted into an optical signal based on the electro-optical effect by a built-in electro-optical modulator, so that the converted optical signal is transmitted to the optical fiber coupler 903, and then the optical fiber coupler 903 distributes and couples the optical signal into the optical filter 902 according to a specific ratio. When performing multi-band signal processing, the optical signal can be guided into the optical filter 902 according to a certain ratio according to the expected processing path of the signals in different frequency bands for preliminary frequency screening, so that the optical filter 902 performs preliminary frequency screening on the optical signal based on the fiber Bragg grating, and removes some optical signals far from the target frequency range. The stray frequency components are removed to make the frequency components of the optical signal more concentrated in the desired frequency band range. At the same time, the intensity and frequency of the optical signal are monitored in real time by the photoelectric sensor, and the photoelectric sensor converts the optical signal into an electrical signal. When the intensity of the optical signal changes due to transmission loss or other factors, the electrical signal output by the photoelectric sensor is transmitted to the variable capacitor array structure 904. The variable capacitor array structure 904 adjusts the electric field applied to the optical fiber coupler 903, the microring resonator 906 and the acousto-optic modulator 905 by changing its own capacitance value according to these signal data. At the same time, when it is necessary to increase the proportion of a certain frequency band optical signal entering the subsequent microring resonator 906, the coupling efficiency is calculated by the following formula:

[0047] ;

[0048] in is the coupling efficiency, is the output optical power, is the input optical power;

[0049] Then the variable capacitor array structure 904 adjusts the electric field accordingly to change the coupling state of the optical fiber coupler 903. The microring resonator 906 uses its own resonance characteristics. When the optical signal passes through, only the optical signal component that matches the adjusted resonance frequency can produce a resonance enhancement effect in the microring, thereby achieving fine screening and adjustment of the optical signal frequency. Multiple groups of microring resonators 906 are located inside the acousto-optic modulator 905. They work together to further improve the accuracy and flexibility of frequency adjustment. Secondly, for the acousto-optic modulator 905, the electric field adjusted by the variable capacitor array structure 904 will change the parameters of the ultrasonic wave in the acousto-optic modulator 905. , so that the acousto-optic modulator 905 changes the diffraction efficiency and frequency offset of the optical signal by changing the ultrasonic parameters based on the acousto-optic effect, and further modulates and fine-tunes the frequency of the optical signal to achieve a more accurate frequency adjustment target, and the prediction data acquisition microprocessor 907 on the computing circuit board continuously receives data from the internal state monitoring signals of the photoelectric sensor, the microring resonator 906 and the acousto-optic modulator 905, and performs real-time analysis and processing on these data, and through the built-in machine learning and prediction model, the prediction data acquisition microprocessor 907 can predict in advance the frequency change trend of the optical signal in the subsequent processing process As well as possible problems (such as the impact of optical element performance drift caused by temperature changes on frequency adjustment), according to the prediction results, the prediction data acquisition microprocessor 907 sends a control instruction to the acousto-optic modulator 905 through the feedback line to adjust the working parameters of the acousto-optic modulator 905 to ensure that the optical signal can be processed according to the expected frequency and quality requirements. After that, the optical signal after a series of adjustments is output through the frequency modulation output multi-channel 908. The frequency modulation output multi-channel 908 can be used to distribute the optical signal to the corresponding output port for output according to different application requirements (such as the output of different frequency band signals in multi-band communication). In terms of the overall structure, precise electric field adjustment is applied to the microring resonator 906 through the variable capacitor array structure 904, so that the resonant frequency of the microring resonator 906 can be adjusted in tiny steps, thereby performing high-precision frequency screening and adjustment on the optical signal, so that its frequency adjustment accuracy can be improved by several times or even higher, effectively solving the problem that the traditional RF amplifier has a large adjustment step and is difficult to achieve high-precision frequency adjustment. At the same time, the frequency switching time can be shortened to a fraction of that of the traditional RF amplifier or even lower, greatly reducing the risk of missing the correct time to receive or send signals, effectively avoiding operation delays, and ensuring efficient and stable operation.

[0050] In the present invention, according to Figure 2 - Figure 4 As shown, the coupling control component 10 includes:

[0051] A coupling controller 101, an electromagnetic adjustment structure 102, a first optical signal monitoring beam splitter 103 and a second optical signal monitoring beam splitter 104. The coupling controller 101 is used to dynamically adjust the optimal coupling ratio in the optical fiber coupler 903 under the feedback data of the photoelectric sensor. The electromagnetic adjustment structure 102 and the variable capacitor array structure 904 are connected through electromagnetic signals.

[0052] The first optical signal monitoring beam splitter 103 and the second optical signal monitoring beam splitter 104 are symmetrically connected at both ends of the electromagnetic regulating structure 102, and form a signal connection through an adaptive feedback network and a coupling controller 101. The wiring harness frame side of the coupling controller 101 is electrically connected to a calibration signal generator 106 and a clock signal generator 105.

[0053] In a specific solution, after the optical signal is preliminarily processed in the photon frequency adjustment component 9, a portion of the optical signal is transmitted to the coupling control component 10, and a small portion of the optical signal is separated from the main optical signal path by the first optical signal monitoring beam splitter 103 and the second optical signal monitoring beam splitter 104 for monitoring, and under the premise of not affecting the quality and intensity of the main optical signal, it is analyzed and confirmed whether the optical signal has frequency drift, intensity fluctuation or phase deviation.

[0054] The detection analysis formulas of the first optical signal monitoring beam splitter 103 and the second optical signal monitoring beam splitter 104 are:

[0055] ;

[0056] in, is the intensity of the monitored optical signal, is the splitting ratio of the first optical signal monitoring beam splitter 103 and the second optical signal monitoring beam splitter 104, is the main light signal strength;

[0057] Next, the electrical signals converted by the first optical signal monitoring beam splitter 103 and the second optical signal monitoring beam splitter 104 are transmitted to the coupling controller 101 through the adaptive feedback network, wherein the adaptive feedback network not only plays the role of signal transmission, but also may perform preliminary processing and integration of the signal to improve the accuracy and reliability of the data. After that, after the coupling controller 101 receives the optical signal monitoring data of the adaptive feedback network, it combines the feedback data obtained from the photoelectric sensor in the photon frequency adjustment component 9 (such as the initial coupling state of the optical fiber coupler 903, the resonant frequency change of the microring resonator 906, and other information) to comprehensively analyze the state of the entire optical signal processing link. , so that the coupling controller 101 compares the difference between the preset optical signal frequency range and intensity standard and the current actual monitoring data, and promptly generates a control instruction according to the analysis result, and sends the instruction to the electromagnetic adjustment structure 102, and the electromagnetic adjustment structure 102 generates an accurate electromagnetic signal according to the received instruction, and the electromagnetic signal acts on the variable capacitor array structure 904. Due to the electrical connection relationship between the variable capacitor array structure 904 and the optical fiber coupler 903, the electromagnetic signal changes the capacitance value of the variable capacitor array structure 904, thereby adjusting the electric field distribution inside the optical fiber coupler 903, so that the coupling ratio of the optical fiber coupler 903 is It changes with the change of the internal electric field, that is, when the above optical signal monitoring data shows that the optical signal intensity is low in a certain frequency band, the coupling controller 101 promptly calculates the coupling ratio that needs to be adjusted, and dynamically adjusts the optical fiber coupler 903 through the electromagnetic adjustment structure 102 and the variable capacitor array structure 904, so that more target frequency band optical signals can smoothly enter the subsequent photon frequency adjustment component 9 for further processing, so as to achieve the best optical signal transmission and frequency adjustment effect. After that, the calibration signal generator 106 generates a calibration signal according to the transmission time interval of the optical signal, which is used to regularly verify and calibrate the working performance of the coupling control component 10 and the above photon frequency adjustment component 9. When there is a deviation or fault, timely adjustment or repair can be made. Secondly, the clock signal generated by the clock signal generator 105 is transmitted to the coupling controller 101, so that the coupling controller 101 can determine the time node for data acquisition, analysis and control instruction sending according to the generated clock signal. In the fast frequency switching operation, the clock signal ensures that the coupling controller 101 can obtain the optical signal monitoring data at a precise time point, and generate and send adjustment instructions in time, so that the entire system can respond to the frequency change demand quickly and accurately, avoid signal confusion or miss the correct reception or transmission time due to time error, and further improve the high precision of frequency regulation.

[0058] In the present invention, according to Figure 2 , Figure 3 and Figure 6 As shown, the input matching adjustment component 8 includes:

[0059] The adaptive impedance matching network 803 , the input matching network guide 801 , the pre-distortion compensator 804 and the connection terminal 805 are all integrated inside the input matching network guide 801 .

[0060] The adaptive impedance matching network 803 is connected to the prediction data acquisition microprocessor 907 through the impedance sensor in cooperation with the connection terminal 805, and the side end of the input matching network guide 801 is connected to the signal output terminal 802, and the signal output terminal 802 is connected to the input RF signal conversion connection terminal 901.

[0061] In a specific solution, the external RF signal first enters the input matching network guide 801, providing a signal access point for the adaptive impedance matching network 803 and the pre-distortion compensator 804, and ensuring the stable transmission of the signal inside. The signal is guided to the adaptive impedance matching network 803 and the pre-distortion compensator 804 for processing in the input matching network guide 801. During the transmission process, the input matching network guide 801 performs some preliminary filtering or buffering processing on the signal to remove interference components such as high-frequency noise or spike pulses in the signal, while ensuring the integrity and stability of the signal to prevent the signal from being distorted or attenuated during the transmission process. Secondly, the impedance sensor in the adaptive impedance matching network 803 starts to work, monitors the impedance characteristics of the input RF signal in real time, and transmits these data to the control unit of the adaptive impedance matching network 803;

[0062] The specific calculation formula for the impedance self-adjustment of the adaptive impedance matching network 803 is:

[0063] ;

[0064] in, is the reflection coefficient, is the impedance of the input RF signal, is the input impedance of the photon frequency adjustment component 9;

[0065] At the same time, through the connection terminal 805, the adaptive impedance matching network 803 establishes a connection with the prediction data acquisition microprocessor 907 in the photon frequency adjustment component 9, receives feedback information from the photon frequency adjustment component 9, and then the adaptive impedance matching network 803 determines the matching degree between the current input RF signal and the subsequent photon frequency adjustment component 9 according to the received impedance data and feedback information, and predicts the direction and amplitude of the impedance adjustment that may be required. Based on the analysis results, the adaptive impedance matching network 803 starts to adjust its own impedance parameters. During the adjustment process, the adaptive impedance matching network 803 will continuously monitor the impedance changes to ensure the accuracy and stability of the impedance matching. Then the adjusted signal is transmitted to the signal output terminal 802 through the input matching network guide 801, and in the adaptive impedance matching network 8 03 while performing impedance matching adjustment, the pre-distortion compensator 804 performs pre-distortion processing on the input RF signal, so that when some optical elements in the photon frequency adjustment component 9 may introduce nonlinear distortion, the pre-distortion compensator 804 performs corresponding amplitude and phase adjustment on the input RF signal according to the pre-established distortion model and the real-time monitored signal parameters, and the signal after the pre-distortion compensation processing is also transmitted to the signal output terminal 802 through the input matching network guide 801, and the RF signal after the impedance matching adjustment of the adaptive impedance matching network 803 and the pre-distortion processing of the pre-distortion compensator 804 is output from the signal output terminal 802 and transmitted to the input RF signal conversion connection terminal 901 of the photon frequency adjustment component 9, and enters the photon frequency adjustment component 9 for subsequent optical signal conversion and frequency adjustment processing.

[0066] In the present invention, according to Figure 1 and Figure 2 As shown, two groups of amplifiers 4 are symmetrically embedded in the front surface of the device body 1. The two groups of amplifiers 4 are located at the left and right ends of the load RF output matching end 7 and are connected to the load RF output matching end 7. Micro axial flow cooling fans 5 are installed at the four internal ends of the device body 1.

[0067] Signal isolators 6 are installed inside the signal transmission cavities of the calibration signal generator 106 and the clock signal generator 105 .

[0068] In a specific scheme, after the optical signal processed by the photon frequency adjustment component 9 and the coupling control component 10 is converted into an RF signal at the load RF output matching end 7, the RF signal is transmitted to the two groups of amplifiers 4. Before the signal reaches the amplifier 4, the load RF output matching end 7 ensures that the impedance of the RF signal matches the input impedance of the amplifier 4 to achieve maximum power transmission and reduce signal reflection. After the two groups of amplifiers 4 amplify the signal respectively, the amplified signal is output to the load RF output matching end 7. Then, the temperature sensor built into the device body 1 is used to monitor the temperature inside the device body 1, so that when the temperature sensor detects that the temperature inside the device body 1 rises to a certain threshold, the micro-axial flow cooling fan 5 starts to start. Secondly, when the calibration signal generated by the calibration signal generator 106 and the clock signal generated by the clock signal generator 105 are transmitted in the signal transmission cavity and reach the signal isolator 6, the signal isolator 6 ensures that the signal is effectively isolated and protected before entering the subsequent sensitive element or complex circuit, effectively ensuring the purity and accuracy of the signal.

[0069] The signal isolator 6, input matching network guide 801, pre-distortion compensator 804, optical filter 902, fiber coupler 903, variable capacitor array structure 904, acousto-optic modulator 905, microring resonator 906, prediction data acquisition microprocessor 907, coupling controller 101, electromagnetic adjustment structure 102, first optical signal monitoring beam splitter 103, second optical signal monitoring beam splitter 104, clock signal generator 105, calibration signal generator 106, wiring diagram of photoelectric sensor and temperature sensor in the present invention belong to the common knowledge in the field, and its working principle is a well-known technology.
