Microstrip Lateral Rf Mems Switch Integrated with Multistep Cpw Transition
نویسنده
چکیده
A new type of microstrip lateral metal-contacting micro-electromechanical systems (MEMS) series switch using an enhanced transition-design technology is proposed and demonstrated. It uses a conductor-backed coplanar waveguide (CBCPW) connected to a microstrip back-to-back MEMS transmission line without any via holes or bonded wires. The RF measurements of this switch show an off-state isolation of 18 dB and an on-state insertion loss of less than 2 dB at 6–27 GHz. In addition, the simplicity of this fabrication process is achieved using deep reactive-ion etching (DRIE), micromachining technology, and silicon-on-insulator (SOI) substrate. © 2004 Wiley Periodicals, Inc.

Design and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation
According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...
