Novel solid-state matrix switch system

Abstract

The invention discloses a novel solid-state matrix switch system. A main switch module comprises a downlink channel, wherein radio frequency signals are input from the ANT, and then are output to PM after passing through the channel switch A and a downlink matrix switch; an uplink channel, wherein radio frequency signals are input from SG, and are divided into eight paths of independent radio frequency signals through a 1-8 broadband power dividing circuit, and is transmitted to an ANT through an uplink additional matrix switch, a channel switch B and a channel switch A; an additional channel,wherein radio frequency signals are input from the SG, and after passing through the power divider circuit, are transmitted to the BANT after passing through the uplink additional matrix switch and the channel switch B; a calibration and backup channel, wherein the radio frequency signals are respectively input from the CAL, the BAK1, and BAK2, and are transmitted to the PM after entering into the calibration and backup matrix switch; a micro-strip coupling circuit, wherein the radio frequency signals are input from an SG end, and output in the form of two paths of signals after passing through the micro-strip coupling circuit, wherein one path of main path signal enters into the power dividing circuit, and the signal after coupling sampling is output to the Couple.

AI Technical Summary

Problems solved by technology

[0003] Early matrix switching systems mainly used relays as channel switching switches, but the frequency of the relays was not high, and the connection and disconnection were realized by mechanical contact contact, and the mechanical life was only 100,000 times.

At the same time, it is limited by the high frequency characteristics of PCB microwave boards

Therefore, the upper limit of the operating frequency can only reach 3GHz, and the loss of the system design is large, the size cannot be miniaturized, and the service life is limited

[0004] The current matrix switch system, considering the contradiction between the loss of radio frequency signals and the isolation index, the product size is relatively large

At the same time, most of the ports are designed with microwave glass insulators, resulting in poor reliability
