Radio frequency(RF)power relays are used to transmit high-power RF signals which produce significant temperature rise.The excessive temperature rise might cause the breakdown of the relay,so thermal analysis methods for RF power relays are of great importance.This paper researches on the thermal analysis method for RF power relays by using coupled simulations and equivalent experiments to analyze the influence that the high-power RF signals have on RF power relays.The results of experiments and simulations show that high-power RF signals will change materials’properties and components’structures,and these changes will deteriorate RF power relays’performance.This paper also researches on the three main failure modes of RF power relays:thermal breakdown,electric breakdown and contact failure.
