Electromechanical switches and relays have been a part of RF/microwave circuits and systems design for some time. They can handle reasonable input power levels for their small sizes, but are typically slower and larger than solid-state switches. Edging closer in speed to solid-state devices, a line of microelectromechanical-systems (MEMS) switches from Analog Devices targets RF/microwave signal switching in a fraction of the size and power consumption of electromechanical relays while promising considerably faster switching speeds and much greater reliability...
