Abstract

The invention relates to a single-pole multi-throw switch with high harmonic suppression, relates to a radio frequency switch device, and belongs to the technical field of basic electrical elements. The high-harmonic suppression switch comprises an input transmission line with one end being an input end, the other end of the input transmission line is connected to one ends of a plurality of harmonic control circuits at the same time, the other end of each harmonic control circuit is connected to one end of a corresponding switch arm, and the other end of each switch arm is an output end. Each harmonic control circuit is composed of an inductor, a capacitor and a tube core, the phase of harmonic waves is changed by selecting proper inductors, capacitors and tube cores for series-parallel connection, and high harmonic suppression is achieved. On the basis of a single-pole double-throw switch, a plurality of harmonic control circuits and switch arms are added to form the single-pole multi-throw switch.

Description

technical field [0001] The invention is a single-pole multi-throw switch with high harmonic suppression, which belongs to the technical field of basic electrical components. Background technique [0002] In electronic communication systems, switches are widely used in radar systems, microwave communication systems and measurement systems, especially in transceiver components. The technical indicators of the switch mainly include: working frequency band, insertion loss, isolation, switching time, harmonic suppression, power capacity, etc., but the traditional switches have poor electrical performance indicators, mainly in: 1) low harmonic suppression; 2 ) Small power capacity; 3) Large area; 4) Large insertion loss, etc., which limits the wide application of such products in complex electromagnetic environments. Contents of the invention [0003] The present invention proposes a single-pole multi-throw switch with high harmonic suppression, and its purpose is to provide a ...
