DESCRIPTION
The FHX13LG/LP, FHX14LG/LP is a Super High Electron Mobility
TM
Transistor(SuperHEMT ) intended for general purpose, ultra-low noise and high
gain amplifiers in the 2-18GHz frequency range. The devices are
packaged in cost effective, low parasitic, hermetically sealed(LG) or epoxy-
sealed(LP) metal-ceramic packages for high volume telecommunication, DBS,
TVRO, VSAT or other low noise applications.
Fujitsu’s stringent Quality Assurance Program assures the highest reliability and con-
sistent performance.

Fujitsu recommends the following conditions for the reliable operation of GaAs FETs:
1. The drain-source operating voltage (V ) should not exceed 2 volts.
DS
2. The forward and reverse gate currents should not exceed 0.2 and -0.05 mA respectively with
gate resistance of 4000W.
3. The operating channel temperature (T ) should not exceed 80¡C.
