Fixed beam directly heated microwave signal detector

Abstract

The invention provides a clamped beam direct heating type microwave signal detector, which comprises a six-port clamped beam coupler, a channel selection switch, a microwave frequency detector, a microwave phase detector and a direct heating type microwave power sensor, wherein the above parts are in cascaded connection to form the clamped beam direct heating type microwave signal detector. The six-port clamped beam coupler consists of a coplanar waveguide, a dielectric layer, an air layer and a clamped beam. The power coupling degree from the first port to the third port and the fourth port of the six-port clamped beam coupler, and the power coupling degree from the first port to the fifth port and the sixth port of the six-port clamped beam coupler are the same with each other. A to-be-measured signal is input via the first port and then is outputted to the direct heating type microwave power sensor via the second port. After that, the signal is outputted to the microwave phase detector via the fourth port and the sixth port and outputted to the channel selection switch via the third port and the fifth port. The seventh port and an eighth port of the channel selection switch are connected with the direct heating type microwave power sensor. The ninth port and the tenth port of the channel selection switch are connected with the microwave frequency detector. In this way, the power, the phase and the frequency of a microwave signal are simultaneously detected.

Description

technical field [0001] The invention provides a fixed beam directly 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 very important in phase-shift keying (PSK), phase-locked loop (PLL), microwave positioning, testing of antenna phase pattern and measuring the phase characteristics of various microwave devices, etc. 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 microwave communication field. The present invention des...
