Overview
The HMC244AG16 is a GaAs MMIC (Monolithic Microwave Integrated Circuit) SP4T (Single-Pole Four-Throw) non-reflective switch designed by Analog Devices Inc. This component operates from DC to 4 GHz, making it suitable for a variety of high-frequency applications. It features a low insertion loss and high isolation, which are critical for maintaining signal integrity in telecommunications, military, and space systems. The switch is integrated with a 2:4 TTL/CMOS compatible decoder, simplifying control with only two control lines and a single positive supply voltage of +5V or +3V.
