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).

Key Features

  • DC to 18 GHz frequency range.
  • High bit rate capability up to 64 Gbps.
  • Low insertion loss:.
  • 0.5 dB (typical) at 8 GHz.
  • 1.0 dB (typical) at 16 GHz.
  • High Input IIP3: 73 dBm (typical).
  • High RF power handling: 33 dBm (maximum).
  • On-resistance: 1.9 Ω (typical).
  • High DC current handling: 200 mA.
  • High switch cycle count: 100 million cycles (minimum).
  • Fast switching time: 200 µs TON (typical).
  • Integrated 3.3 V driver for simple control with para.
