Analog Devices ADGM1304 Product Info

The ADGM1304 is a wideband, single-pole, four-throw (SP4T) switch, fabricated using Analog Devices, Inc., microelectro-mechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational from 0 Hz/dc to 14 GHz, making the ADGM1304 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 a switch that can be controlled by a parallel interface and a serial peripheral interface (SPI). All four switches are independently controllable.

The device is packaged in a 24-lead, 5 mm × 4 mm × 0.95 mm, lead frame chip-scale package (LFCSP).

To ensure optimum operation of the ADGM1304, the Critical Operational Requirements section must be followed exactly.

The on resistance (R_ON) performance of the ADGM1304 is affected by device to device variation, channel to channel variation, cycle actuations, settling time post turn on, bias voltage, and temperature changes.
