Abstract

The invention belongs to the technical field of electromechanical switches, and relates to a radio frequency coaxial switch. A fail-safe single-pole double-throw radio frequency coaxial switch, including an electromagnetic control system and a microwave transmission system; the electromagnetic control system includes a relay assembly and a cover assembly; the microwave transmission system includes a transmission cavity assembly; The electromagnetic field generated by electricity controls the cover assembly, so as to realize the conduction and disconnection of the microwave channel. The fail-safe single-pole double-throw radio frequency switch of the present invention eliminates the use of moving parts such as springs and shrapnel through the design of a new electromagnetic control system, improves the reliability of the radio frequency coaxial switch, and increases the switching life.

Description

technical field [0001] The invention belongs to the technical field of electromechanical switches, and relates to a radio frequency coaxial switch. Background technique [0002] The fail-safe SPDT RF coaxial switch, as a microwave passive device, mainly realizes the transmission and switching of microwave signals, and is widely used in automatic test systems, radar and communication fields. The invention patent with application number 201810500302.3 discloses a fail-safe high-power single-pole double-throw coaxial switch, including coil mounting plate, iron core, coil, magnetic steel, shell, armature block, pressure piece, cover plate, transmission reed, Media seat, spring and pin. The device mainly uses the structural design of the spring and shrapnel to realize the switching function. During the switching process of the spring and the shrapnel, there will be fatigue life, the switching reliability is low, and the switching life is short. Contents of the invention [00...
