Overview
The HMC349AMS8G is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (PHEMT), single-pole, double throw (SPDT) switch designed by Analog Devices Inc. This component is specified to operate from 100 MHz to 4 GHz, making it highly suitable for various wireless and cellular infrastructure applications. It offers high isolation of 57 dB, low insertion loss of 0.9 dB, high input IP3 of 52 dBm, and high input P1dB of 34 dBm. The switch operates with a single positive supply voltage from 3 V to 5 V and features a CMOS-/TTL-compatible control interface.
