Fixed beam T-junction directly heated microwave signal detector

Abstract

The invention provides a clamped beam T-shaped junction direct heating type microwave signal detector. The clamped beam T-shaped junction direct heating type microwave signal detector is constituted by cascading a six-interface clamped beam coupler, a channel selection switch, a microwave frequency detector, a microwave phase detector and a direct heating type microwave power sensor; the coplanar waveguide length between two clamped beams is lambda / 4; the power coupling from a first interface to a third interface and to a fourth interface and from the first interface to a fifth interface and to a sixth interface of the six-interface clamped beam coupler is the same respectively, and a signal to be detected is input through the first interface, is output to the direct heating type microwave power sensor through a second interface, is output to the microwave phase detector through the fourth interface and the sixth interface, and is output to the channel selection switch through the third interface and the fifth interface; a seventh interface and an eighth interface of the channel selection switch are connected to the direct heating type microwave power sensor, and a ninth interface and a tenth interface of the channel selection switch are connected to the microwave frequency detector; the purpose of simultaneously detecting the power, the phase and the frequency of a microwave signal through one chip is achieved.

Description

technical field [0001] The invention provides a fixed beam T-junction direct heating microwave signal detector, which belongs to the technical field of micro-electromechanical systems. Background technique [0002] Under the background of modern technology, microwave signal detection is widely used in phase modulator, phase shift keying (PSK), phase locked loop (PLL), microwave positioning, antenna phase pattern test, near field diagnosis, and measurement of various microwave devices. Phase characteristics and so on have a very wide range of applications. These systems urgently need electronic devices with light weight, small size, low power consumption and high integration in practical applications. However, the existing microwave power, phase, and frequency detectors are all discrete circuits and have a large volume. Therefore, a system that can realize integrated detection of the three microwave parameters is urgently needed to meet the application requirements of the mi...
