Problems solved by technology

[0002] Most of the microwave switches that can be seen on the market are mechanical structures with complex structures, convenient operation, few switching channels, and heavy weight; although recently some people use PIN diodes to make multi-channel microwave switches, such as ZL200410052278. And power amplifier hot backup and mutual aid system and implementation method), but many power dividers are used, which makes the structure complex and the frequency range small
Today, modern RF radio frequency and microwave measuring instruments are becoming more and more broadband, and it is difficult to adapt, so we have developed and designed a new multi-channel microwave switch system

Abstract

The invention relates to a microwave switch, in particular to a multiway microwave switch system and a method for realizing the same. The multiway microwave switch system is assembled according to the topology theory; the method comprises the following steps that: an RF input end of a first electronic switch is connected with a high-frequency connector through a section of transmission lines; two output ends RF1 and RF2 are respectively connected with RF input ends of a second electronic switch and a third electronic switch by a section of transmission lines; by parity of reasoning, the transmission lines of the RF output ends of a plurality of final electronic switches are connected with the high-frequency connector; each electronic switch has two control ends A and B; and a channel is switched by the height of power levels on the two ends A and B. The multiway microwave switch system is suitable for various RF radio frequency and microwave switch systems and also for various RF radio frequency communication systems and has the characteristics of quick reaction, small loss, high insulation, convenient operation, etc.
