ADGM1121 Switch

Analog Devices' ADGM1121 0 Hz/DC to 18 GHz, DPDT, MEMS switch is suited for various RF and precision equipment switching

Image of Analog Devices' ADGM1121 SwitchThe ADGM1121 is a wideband double-pole, double-throw (DPDT) switch fabricated using ADI's 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 on-resistance (RON) performance of the ADGM1121 is affected by part-to-part or channel-to-channel variation, cycle actuation, settling time post turn-on, bias voltage, and temperature changes.

The EVAL-ADGM1121SDZ is available for evaluation of the ADFM1121DPDT MEMS switch. It comes fitted with connectors for RF and control signals as well as links to control the operation of the switch and evaluate its performance. For SPI, the EVAL-ADGM1121SDZ connects to the USB port of a PC through the system demonstration platform (SDP) board.
