摘要
This paper presents the design, fabrication and testing of capacitive copper RF MEMS switches with various hinge geometries, fabricated on high-resistivity silicon substrate. The switches were fabricated using a simple low-cost four-mask process and 0.6-1.0mum thick membranes were made out of sputtered copper. The capacitive airgap in between the membrane and the signal line is 1.5-2.0mum. The lowest actuation voltage measured on the fabricated switches is 9V. The measured insertion loss of a fabricated switch and its associated transmission line was 0.9dB (mainly contributed by the transmission line Itself) and the isolation was measured to be 25dB at 40GHz.
