GENERAL DESCRIPTION
The ADGM1004 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 down to 0 Hz/dc,
making it an ideal solution for a wide range of RF and precision
equipment switching needs.
An integrated control chip generates the high voltage necessary
to electrostatically actuate the switch via a complementary metal-
oxide semiconductor (CMOS)-/low voltage transistor-transistor
logic (LVTTL)-compatible parallel interface. All four switches are
independently controllable.
The device is packaged in a 24-lead, 5 mm × 4 mm × 1.45 mm
lead frame chip-scale package (LFCSP).
