Gold Gate Metallization for High Reliability
DESCRIPTION
The FHX04X, FHX05X, FHX06X are High Electron Mobility
Transistors (HEMT) intended for general purpose, low noise and high
gain amplifiers in the 2-18GHz frequency range. The devices are well
suited for telecommunication, DBS, TVRO, VSAT or other low noise
applications.
Eudyna’s stringent Quality Assurance Program assures the highest
reliability and consistent performance.

Eudyna 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.
