DESCRIPTION AND APPLICATIONS
GATE
BOND PAD
The FP4050 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs)
Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-
write 0.50 um by 400 um Schottky barrier gate. The recessed 鈥渕ushroom鈥?gate structure minimizes
parasitic gate-source and gate resistances. The FP4050 features Si3N4 passivation.
Typical applications include commercial and military high-performance power amplifiers, including
SATCOM uplink transmitters, PCS/Cellular low-voltage high-efficiency output amplifiers, and
medium-haul digital radio transmitters. This device is also suitable as a power stage for WLAN and
ISM band spread spectrum applications.
