Problems solved by technology

[0003] Technical problem: The phase detector in the traditional microwave circuit not only needs to know the frequency of the signal to be tested, has DC power consumption, but also completely consumes the input detection signal; a six-port fixed beam coupler is used to couple a small part of the signal for Frequency detection and phase detection, and most of the detection signals can be input to the next-level processing circuit to realize 0-360° phase online detection of unknown frequency signals, and has the benefit of low power consumption
