GENERAL DESCRIPTION
The HMC349AMS8G is a gallium arsenide (GaAs), pseudo-
morphic high electron mobility transistor (PHEMT), single-pole,
double throw (SPDT) switch specified from 100 MHz to 4 GHz.
The HMC349AMS8G is well suited for cellular infrastructure
applications by yielding 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.
