Overview
The ADGM1304JCPZ-RL7 is a wideband, single-pole, four-throw (SP4T) switch developed by Analog Devices Inc. using microelectromechanical system (MEMS) switch technology. This device is designed to offer high power handling, low loss, and low distortion across a wide frequency range from 0 Hz/dc to 14 GHz. The integrated driver chip generates the high voltage necessary to electrostatically actuate the switch, which can be controlled via a CMOS-/LVTTL-compatible parallel interface and a serial peripheral interface (SPI). All four switches are independently controllable, making the ADGM1304 an ideal solution for various RF and precision equipment switching needs.
