Original MEMS-Based Single Pole Double Throw Topology for Millimeter Wave Space Communications

This paper presents the design, fabrication and characterization of a MEMS-Based Single Pole Double Throw (SPDT) circuit for millimeterwave applications. High performances are achieved thanks to an original circuit design based on MEMS synthesized quarter wave line combined with surface and bulk micromachinings of silicon. 0.6 dB insertion loss of the SPDT circuit was measured with an isolation of 21dB at 30GHz.
