HMC349AMS8GE Product Details

The HMC349AMS8GE 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 HMC349AMS8GE is well suited for cellular infrastructure applications by yielding high isolation of 57 dB, low insertionloss of 0.9 dB, high input IP3 of 52 dBm, and high input P1dB of 34 dBm.

The HMC349AMS8GE operates with a single positive supply voltage from 3 V to 5 V and provides a CMOS-/TTL-compatible control interface.

The HMC349AMS8GE comes in an 8-lead mini small outline package with an exposed pad.
