Latched microswitches in laminates for high power 0-6.5 GHz applications

A microswitch designed for high power radio-frequency (RF) applications is presented. A unique 3D transmission line is combined with a robust latched direct contact switch in this RF switch design. Each unit is fabricated in laminate panels before being singulated into pre-packaged micro-RF switches. High power RF tests reached 15 W at 1.9 GHz for this device. The switch has a good RF performance with −0.296 dB insertion loss and −22.03 dB isolation at 6.56 GHz.
