Abstract

Some embodiments of the present disclosure disclose a directional coupler and a microwave device, which relate to the field of microwave technology and are used to increase bandwidth and reduce loss, so as to meet the requirement of large bandwidth of a 5G network. The directional coupler includes a housing, and a first section of parallel coupling lines, a second section of parallel coupling lines, and a third section of parallel coupling lines arranged in sequence in the housing; wherein, the first section of parallel coupling lines Correspondingly connected to the second parallel coupled line through the first connecting section; correspondingly connected to the third parallel coupled line through the second connecting section; on the side wall of the housing There are slots corresponding to the first connecting section and the second connecting section respectively; the orthographic projections of the first connecting section and the second connecting section on the side wall are located in the corresponding slots within the orthographic projection on the side walls. The directional coupler and microwave device provided by some embodiments of the present disclosure are used for microwave signal transmission.

Description

technical field [0001] The present disclosure relates to the field of microwave technology, in particular to a directional coupler and a microwave device. Background technique [0002] Directional coupler is a widely used microwave device, mainly including Betz hole coupler, porous directional coupler, Schwinger (Schwinger) coupler, 3 decibel (referred to as dB) coupler and coupling line type directional coupler, etc. [0003] The fifth-generation mobile communication technology (5th-Generation, 5G for short) is the latest generation of cellular mobile communication technology. 3G) and the extension of the second-generation mobile communication technology (2th-Generation, referred to as 2G) system. The performance goals of 5G are high data rates, reduced latency, energy savings, cost reductions, increased system capacity, and large-scale device connectivity. [0004] However, the directional coupler in the related art has a small power capacity and a narrow frequency band...
