Novel RF MEMS Switches

This paper reviews three novel RF MEMS ohmic contact switches, each being designed for specific applications. All three were developed at Imperial College London. The first is a packaged single-pole double throw (SPDT) version intended for space applications, operating from DC to 6 GHz; the second is a single-pole single throw (SPST) switch for high power applications in the 40 to 60 GHz band; and the third is a single- pole eight throw (SP8T) switch for signal routing applications, operating from DC to 20 GHz. The design, and measurements for all three unique solutions will be briefly summarized.
