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...

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The existing double-pole double-throw radio frequency switch requires a group of reeds to work at the same time. In order to realize this movement, the usual double-pole double-throw radio frequency switch needs 4 or 2 driving relays to realize. The number and types of relays directly affect the size and weight of the DPDT RF switch, and then to a certain extent affect the scope of use of the DPDT RF switch. Moreover, in special fields such as aerospace...
