Renaissance Electronics Corp. (Harvard, MA) has introduced an 8 x 8 switch matrix based on a total of 80 single-pole, double-throw (SPDT) microelectromechanical-system (MEMS) switches. The MEMS devices are fabricated with a conventional silicon micromachining approach to produce a high-force cantilever switch structure that is contained within a wafer-bonded hermetic package. Rated for a life expectancy of more than 100 billion switching cycles, the switch matrix handles 2 W CW input power from DC to 2.5 GHz with 6 dB insertion loss and 40 dB isolation. The compact unit measures 7.85 x 7.43 x 2.8 in. with female SMA connectors and provides blocking type switching without power splitters. It achieves switching speed of less than 50 microseconds and draws only 10 mA current at +5 VDC upon actuation. The switch matrix, which is suitable for applications in communications, military, and test and measurement systems, incorporates a TCP/IP Ethernet control interface.
