The radio frequency receiving module 1 includes a low noise amplifier 11, a quadrature mixer 12, a low pass amplifier 13, a power amplifier 14, and a first filter 15. The radio frequency amplification processing module 2 comprises a radio frequency processing unit 16 and a power control unit 23; wherein the radio frequency processing unit 16 comprises a detector 16a, a limiter 16b and a second frequency comparator 16c connected in sequence; the power control unit 23 includes a second power comparator 16d, a power controller 16e, and a power comparison filter 16f, which are sequentially connected. The radio frequency transmitting module 3 includes a radio frequency demodulator 17, a second filter 18, a first power comparator 19, a power limiter 20, a power feedback amplifier 21, a phase-locked loop synthesizer 21a, a reference source 21b, a radio frequency sampler 21c, a third filter 21d, a first frequency comparator 21e, a waveform shaping comparator 21f, and an output shaping filter 22.
In the radio frequency receiving module 1, a low noise amplifier 11, a quadrature mixer 12, a low pass amplifier 13, a power amplifier 14, and a first filter 15 are sequentially connected. In the rf processing unit 16, a detector 16a, a limiter 16b, and a second frequency comparator 16c are sequentially connected. The first filter 15 of the radio frequency receiving module 1 is connected to a detector 16a of the radio frequency processing unit 16. The second frequency comparator 16c is connected to the radio frequency demodulator 17. The radio frequency demodulator 17 is also connected to the output shaping filter 22 and the second filter 18, respectively.
The second filter 18, the first power comparator 19, the power limiter 20 and the power feedback amplifier 21 are sequentially connected; the power feedback amplifier 21 is also connected to the output shaping filter 22 and the phase-locked loop synthesizer 21a, respectively; the phase-locked loop synthesizer 21a is further connected to the reference source 21b, the quadrature mixer 12 and the radio frequency sampler 21c, respectively; the radio frequency sampler 21c is also connected to the low noise amplifier 11 and the third filter 21d, respectively; the third filter 21d, the first frequency comparator 21e, and the waveform shaping comparator 21f are sequentially connected in order; the waveform shaping comparator 21f is also connected to the second power comparator 16d of the power control unit 23. In the power control unit 23, the second power comparator 16d, the power controller 16e, and the power comparison filter 16f are sequentially connected in this order. The power controller 16e is also connected to the limiter 16 b; the power comparison filter 16f is also connected to the radio frequency demodulator 17.
The digital control module 4 is connected to the power feedback amplifier 21, the first frequency comparator 21e, the waveform shaping comparator 21f, the second power comparator 16d, and the power management module 5, respectively.
The radio frequency receiving module 1 is a receiving circuit of a 9kH-18GHz radio frequency signal. Wherein the low noise amplifier 11 is configured to perform low noise differential amplification on the received rf signal and output the amplified signal to the quadrature mixer 12 and the rf sampler 21c in two paths, respectively. The quadrature mixer 12 is configured to mix and convert the quadrature radio frequency signal to output to the low-pass amplifier 13. The low-pass amplifier 13 attenuates the low-pass filtered smaller signal to the power amplifier 14. The power amplifier 14 performs power amplification processing on the radio frequency signal, reaches a required design amplitude, and outputs the signal to the first filter 15. The first filter 15 filters the power-amplified rf signal and outputs the filtered rf signal to the rf processing unit 16. The radio frequency processing unit 16 first detects the input radio frequency signal by using the detector 16a, and then clips waveforms of different magnitudes by using the limiter 16b after the detection. The limiter 16b outputs a stable radio frequency signal to the second frequency comparator 16c under the combined action of the adjustment of the power controller 16e and the detector 16 a.

The second filter 18 filters the rf modulated signal, filters the rf clutter signal, and outputs the filtered rf clutter signal to the first power comparator 19; the first power comparator 19 adjusts the power of the rf signal and outputs the adjusted rf signal to the power limiter 20. The power limiter 20 controls the radio frequency signal to a desired amplitude to prevent the power feedback amplifier 21 from being burned out due to an excessive power amplitude. After the amplitude control, the modulated radio frequency signal is output to the power feedback amplifier 21, the power feedback amplifier 21 performs control adjustment and feedback monitoring on the radio frequency signal with the amplitude adjusted through the digital control module 4, and the radio frequency signal is compared with the phase-locked loop synthesizer 21a to complete radio frequency phase locking, so that a stable radio frequency signal is formed to the output shaping filter 22, and is output to an antenna after being shaped by the output waveform of the output shaping filter 22, and radio frequency output is performed through an external antenna.
Specifically, the radio frequency transmitting module 3 is a transmitting circuit in the form of a direct phase-locked loop synthesizer 21a, works at 9kHz to 18GHz, and outputs a stable and reliable radio frequency waveform. The radio frequency transmitting module 3 uses the local oscillation frequency as a reference source 21b, compares and samples the local oscillation frequency through the low noise amplifier 11 and the radio frequency sampler 21c to form a stable synthesized frequency source, and then sequentially filters, compares and shapes the waveform of the radio frequency signal which is digitally controlled through the third filter 21d, the first frequency comparator 21e, the waveform shaping comparator 21f, the second power comparator 16d, the power controller 16e and the power comparing filter 16f, and then shapes and outputs the radio frequency signal, and finely controls the working states and parameters of the radio frequency receiving module 1, the radio frequency amplifying processing module 2 and the radio frequency transmitting module 3 through the digital control module 4, thereby ensuring the stability and reliability of the output frequency.
