Abstract

The invention relates to a waveguide detection unit of a magnetic excitation coupling mechanism in the field of microwave technology, which solves the problems of the existing waveguide coupling detectors, such as large volume and weight, difficulty in integration, special processing of waveguide cavities, and the like. The invention uses a magnetic excitation coupling mechanism to replace the traditional electric field excitation coupling to realize the power monitoring of the main mode of the waveguide; a planar probe ring is used to replace the coaxial probe, which can greatly reduce the thickness of the detector; a low temperature co-fired ceramic (LTCC) is used as an integrated The chemical structure replaces the all-metal packaging structure of discrete devices. The invention has small structural size, low weight, and integrated ceramic structure without special surface treatment and is easy to integrate, and is suitable for miniaturized and highly integrated microwave and millimeter wave detection circuits and systems.

Description

technical field [0001] The invention relates to a circuit device for microwave power monitoring in a microwave circuit and system, in particular to a waveguide coupling detection unit [0002] technical background [0003] In recent years, with the rapid development of mobile communication, satellite communication and radar technology, more and more new technologies have been applied to the consumer market. The ever-increasing user demand has brought about explosive data bandwidth expansion, which has promoted the existing communication With the improvement of the operating frequency of equipment, for satellite communications, Ka-band broadband applications have gradually entered the mainstream. In the future, 5G mobile communications will also target the millimeter-wave frequency band. [0004] For millimeter wave signal transmission, with the increase of operating frequency and power, it is particularly important to reduce the interconnection loss between various devices. ...
