LPS200P70

PACKAGED LOW NOISE PHEMT

• DESCRIPTION AND APPLICATIONS

The LPS200P70 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 high dynamic range. The LPS200’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 for commercial applications including

Cellular/PCS systems and broad band commercial instrumentation.
