DESCRIPTION AND APPLICATIONS The FP2250QFN is a high performance, leadless, encapsulated packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) pseudomorphic High Electron Mobility Transistor (pHEMT). It utilizes a 0.25 µm x 2250 µm Schottky barrier gate, defined by electronbeam photolithography. The recessed “mushroom” gate structure minimizes parasitic gate-source and gate resistance. The epitaxial structure and processing have been optimized for reliable highpower applications.
