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. The device is packaged in a 24-lead, 5 mm × 4 mm × 1 mm land grid array (LGA) package. To ensure optimum operation of the ADGM1121, see the Critical Operational Requirements section. The on-resistance (RON) performance of the ADGM1121 is affected by part-to-part variation, channel-to-channel variation, cycle actuations, settling time post turn on, bias voltage, and temperature changes.
