Realizing method and realizing device of six-port phase detector

Abstract

The invention provides a realizing method of a six-port phase detector. The realizing method of the six-port phase detector is used for detecting a phase of a radio frequency (RF) signal. According to the realizing method of the six-port phase detector, firstly, a traditional circuit model is modified, then according to the amplitude and a phase of a vector quantity and a base band vector quantity F related to a RF unknown signal, a certain reference signal is generated, can be used for measuring the phase of the unknown signal and is applied to phase verification and phase sequence verification of microwaves, a receiver and a radar. A traditional phase detection device is prone to external disturbance, and is low in signal to noise ratio and sensitivity and complex in system constitution. The realizing method of a six-port phase detector is high in sensitivity and signal to noise ratio, good in stability, strong in capacity of resisting disturbance, and simple and reasonable in structure, thereby obtaining an optimal phase detection result.
