A device for improving the reliability of radio frequency relay

RF relay is a kind of relay that can transmit and switch RF signal, also called mechanical switch. With the rapid development of RF microwave technology, the signal frequency is increasing, and the requirements for insertion loss, isolation, and burn-in resistance of the switch are getting higher. These indicators are not available at the same time for electronic switches, so radio frequency coaxial relay is widely used. This device uses a RF relay online detection method that can effectively detect its conduction abnormalities and reset, which can improve its stability and reliability, thus improving the reliability of radar, electronic countermeasures and other systems using this module.
