An RF microelectromechanical-systems (MEMS) switch boasts the high-frequency characteristics of electromechanical relays with a life expectancy that rivals solidstate relays. Driven by an electrostatic drive system, the 2SMES-01 is rated for 100 million operations at 0.5 mA and 0.5-VDC. It has been tested over 1 billion cycles. At 10 GHz, the 50- 2SMES-01 features 30 dB of isolation. It exhibits 1 dB insertion loss and 10 dB return loss. The switch consumes 10 W. The relay is comprised of two SPST-NO silicon chips. They are packaged together for SPDT or DPST-NO operation in an enclosure measuring just 5.2 x 3.0 x 1.8 mm. The switch was developed to meet the needs of the automated-test-equipment (ATE) market.
