The LP3000 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam directwrite 0.25 m by 3000 m Schottky barrier gate. The recessed "mushroom" gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure and processing have been optimized for reliable high-power applications. The LP3000 is also available in a P100 flanged ceramic package and in the low cost plastic SOT89 package. Typical applications include commercial and other high-performance power amplifiers.
