GENERAL DESCRIPTION

The ADGM1304 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 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 (RON) 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.
