LP7512P70
PACKAGED ULTRA LOW NOISE PHEMT
• DESCRIPTION AND APPLICATIONS
The LP7512P70 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide
(AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an
Electron-Beam direct-write 0.25 µm by 200 µm Schottky barrier gate. The recessed “mushroom”
Ti/Pt/Au gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure
and processing have been optimized for optimum low noise performance. The LP7512’s active
areas are passivated with Si₃N₄, and the P70 ceramic package is ideal for low-cost, high-performance
applications that require a surface-mount package.
Typical applications include low noise receiver preamplifiers in wireless systems.
