A Single Relay Double Pole Double Throw RF Switch

Abstract

The present invention proposes a single-relay double-pole double-throw radio frequency switch, which includes a terminal 1, a control board 2, a mounting screw 3, a magnetic latching relay 4 built into a magnetic steel, a mounting board 5, a microwave assembly 6, a pressure reed 7, a drive The reed 8 and the shell 9; the control board 2, the relay 4 built in the magnetic steel, the mounting plate 5, and the microwave component 6 are connected together by the mounting screw 3 to form a whole. The single-relay double-pole double-throw radio frequency switch of the present invention is driven by a single relay, and utilizes a lever principle to drive the reed of the double-pole double-throw radio frequency switch to realize normal operation. The reduction of driving relays helps to reduce the size and weight of the double pole double throw RF switch.

Description

technical field [0001] The invention relates to the field of electromechanical coaxial switches, in particular to a single-relay double-pole double-throw radio frequency switch. Background technique [0002] As the frequency of analog signals and the rate of digital signals continue to rise, coaxial switches have more and more uses and wider application fields. Double-pole double-throw RF switches, as a kind of coaxial switches, are widely used in various fields , such as wireless communication, satellite communication, satellite navigation, radar system, automatic control system, automatic test equipment (ATE), etc. [0003] With the continuous development and progress of science and technology, especially the development of aerospace and precision technology, the requirements for the components used are getting higher and higher, and double-pole double-throw radio frequency switches as components in these fields have also been proposed more and more More requirements, suc...

Problems solved by technology

Due to the number of driving relays, although various types of driving relays have been developed rapidly and there are more and more forms, the number of relays has become an obstacle to the weight and volume optimization of double-pole double-throw RF switches. These two types of double-pole The double-throw RF switch has a bottleneck in terms of weight and volume optimization, and the increase in the number of relays will also increase the cost and complexity of production and assembly of the double-pole double-throw RF switch
