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 of the data sheet.
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.
APPLICATIONS
- ATE load and probe boards
- DC with high speed loopback testing
- High speed SerDes, PICe Gen4/5, USB4, PAM4
- Relay replacements
- Reconfigurable filters/attenuators
- Military and microwave radios
- Cellular infrastructure: 5G mm wave

Evaluation Kits 1
EVAL-ADGM1121
Evaluating the ADGM1121 0 Hz/DC to 16 GHz, 2 x DPDT, MEMS Switch
Product Detail
The user guide describes the EVAL-ADGM1121SDZ for the ADGM1121, a dual-chip, RF switching solution containing a double-pole, double-throw (DPDT), microelectromechanical systems (MEMS) switch, and a control chip co-packaged in a compact, 5.00 mm × 4.00 mm × 1.00 mm, LGA package.
The DPDT switch uses Analog Devices' MEMS switch technology, providing optimum performance in terms of bandwidth, power handling capability, and linearity for RF applications. The control chip generates the high-voltage signals needed for the MEMS switch and allows the user to control its operation through a simple and flexible complementary metal-oxide semiconductor (CMOS)/low voltage transistor to transistor logic (LVTTL)-compliant parallel-interface as well as through a serial-peripheral interface (SPI). It is possible to daisy-chain multiple ADGM1121 devices together to enable the configuration of multiple devices with a minimal number of digital lines.
For SPI, the EVAL-ADGM1121SDZ connects to the USB port of a PC through the system demonstration platform (SDP) board. The EVAL-SDP-CB1Z board (SDP-B controller board) is available to order at the Analog Devices website.
The EVAL-ADGM1121SDZ 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 full details on the ADGM1121, see the ADGM1121 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADGM1121SDZ.
