GENERAL DESCRIPTION

The ADGM1121 is a wideband, double-pole, double-throw (DPDT)

switch, fabricated using Analog Devices' microelectromechanical

system (MEMS) switch technology. This technology enables a small

form factor, wide RF bandwidth, highly linear and low insertion loss

switch that is operational down to 0 Hz/DC, making it an ideal

solution for a wide range of RF and precision equipment switching

needs. An integrated driver chip generates a high voltage to electrostatically

actuate switch that can be controlled by a parallel interface and

a serial peripheral interface (SPI). All switches are independently controllable.

FEATURES
