3mm × 3mm SP4T MEMS Switch, 0Hz/DC to 30GHz

The ADGM3144 is a wideband, single-pole, four-throw (SP4T) switch, fabricated using Analog Devices, Inc., microelectromechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational down to 0Hz/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 or a serial peripheral interface (SPI). All switches are independently controllable.

The device is packaged in a 24-lead, 3mm × 3mm × 1.5mm land grid array package. To ensure optimum operation of the ADGM3144 refer to the Critical Operational Requirements section. The on-resistance (RON) performance of the ADGM3144 is affected by part-to-part variation, channel-to-channel variation, cycle actuations, settling time post turn on, bias voltage, and temperature changes.
