FPD7612
GENERAL PURPOSE pHEMT
The FPD7612 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility
Transistor (pHEMT), featuring a 0.25mx200m Schottky barrier gate,
defined by high-resolution stepper-based photolithography. The recessed
gate structure minimizes parasitics to optimize performance. The epitaxial
structure and processing have been optimized for reliable high-power
applications.
