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 (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.
APPLICATIONS
- Relay replacements
- Automatic test equipment: RF/high speed digital and mixed signals
- Load and probe boards: RF/high speed digital and mixed signals
