FPD750 Overview
FPD750 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility Transistor (PHEMT), featuring a 0.25 µm by 750 µm Schottky barrier gate, defined by highresolution stepper-based photolithography. The double recessed gate structure minimizes parasitics to optimize performance. The epitaxial structure and processing have been optimized for reliable high-power applications.
