DESCRIPTION
The FHX13LG, FHX14LG is a Super High Electron Mobility 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 metal-ceramic package for high volume telecommunication, TVRO, VSAT or
other low noise applications.
Fujitsu’s stringent Quality Assurance Program assures the highest reliability and
consistent performance.

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