The LP7512 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 200 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 ultra low noise and usable gain to 40 GHz. The LP7512 also features Si3 N4 passivation and is available in a variety of packages. Typical applications include low noise receiver preamplifiers for commercial applications including wireless systems and radio link systems.
