Problems solved by technology

[0004] The existing single-pole double-throw radio frequency coaxial switch realizes the function of gating one channel of two microwave signals by connecting or disconnecting the two ends of the relay armature assembly with the transmission reed, but it is impossible to determine which channel is conducting and which channel is connected. All the way disconnected
It brings a lot of inconvenience in practical application

Abstract

The invention belongs to the technical field of electromechanical switches, and relates to a feedback device and a radio frequency coaxial switch. The feedback device comprises two groups of elastic sheet assembly and an elastic sheet base. Each of the elastic sheet assembly and the elastic sheet base is of an injection molding integrated structure. The elastic sheet assemblies are symmetrically arranged on the elastic sheet base. A single-pole double-throw radio frequency coaxial switch comprises a microwave transmission system, a relay system, a feedback device circuit board and a control interface. The microwave transmission system is connected with the relay system. The feedback device comprises the two groups of elastic sheet assemblies, the lower parts of the elastic sheet assembliesare connected with an armature assembly of the relay system, and the upper parts of the elastic sheet assemblies are connected with the circuit board. A circuit communicating with the circuit board is connected with two pins of the control interface. According to the invention, the conduction and disconnection states of a microwave path of the radio frequency coaxial switch are fed back through connection and disconnection of the two metal feedback elastic sheets.

Description

technical field [0001] The invention belongs to the technical field of electromechanical switches, and relates to a feedback device and a radio frequency coaxial switch. Background technique [0002] As a microwave passive device, the SPDT RF coaxial switch mainly realizes the transmission and switching of microwave signals, and is widely used in automatic test systems, radar and communication fields. [0003] Single-pole double-throw RF coaxial switch realizes the function of one signal gating two signals, one channel is turned on and one channel is disconnected when it is not powered on, when it is powered on, the original conducting channel is broken Open, the original disconnected path is turned on. Single pole double throw radio frequency coaxial switch is mainly composed of electromagnetic control system, transmission mechanism and microwave transmission system. The electromagnetic control system realizes the on-off state switching of the two channels by generating e...
