A metal contact RF MEMS switch based on single crystal silicon is presented in this article. Performance of the switch is demonstrated numerically in simulations. The mN-level contact and release forces are achieved. Pull-in voltage is calculated to be 40V. 1.5mN contact force and 1.2mN release force are achieved when actuation voltage is 50V. The isolation and insertion loss are better than −30.8dB...
This paper presents an electrostatic RF microelectromechanical systems (MEMS) metal contact switch based on a tethered cantilever topology. The use of tethers results in a design that has low sensitivity to stress gradients, biaxial stresses, and temperature. A switch with a footprint of 160 × 190 μm2 and based on a 8-μm-thick gold cantilever with an Au/Ru contact is implemented on a high-resistivity...
