Problems solved by technology

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 in the microwave communication field.

Abstract

The invention relates to a clamped-beam direct-heating type microwave signal detecting instrument, comprising the four modules: a sensor, an analog-digital converter, an MCS51 single-chip microcomputer and a liquid crystal display; the sensor is formed by cascading a six-port clamped beam coupler, a channel selector switch, a microwave frequency detector, a microwave phase detector, and a direct heating type microwave power sensor; for the six-port clamped beam coupler, there is equal power coupling degree from a first port to a third port and a fourth port share, and from the first port to a fifth port and a sixth port, a signal is input from the first port, is discharged out of the direct heating type microwave power sensor from the second port, is discharged out of the microwave phase detector via the fourth port and the sixth port, and is discharged to the channel selector switch via the third port and the fifth port; seventh and eighth ports of the channel selector are connected to the direct heating type microwave power sensor, and ninth and tenth ports of the channel selector switch are connected to the microwave frequency detector; the power, phase and frequency of a microwave signal are detected at the same time.

Description

technical field [0001] The invention provides a fixed beam directly heating microwave signal detection instrument, 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 i...
