Abstract:
1. A radio frequency switch circuit comprising: a radio frequency input; a control input; a radio frequency output; and a microelectromechanical switch connected to said radio frequency input and output and control input and comprising a multilayer ceramic substrate having embedded microstrip and interconnect structures among different layers; a low loss photodefinable dielectric planarizing layer formed over the ceramic substrate; a photodefined conductor printed over the low loss dielectric planarizing layer and formed into a switch, and further comprising a biasing actuator connected to said control input, and a deflectable member formed over the biasing actuator and movable into a closed circuit position upon actuation of said control input and operatively connected to said radio frequency input and output when in the closed circuit position.
