Description

`The LPD200MX 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" 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 LPD200's active areas are passivated with Si₃N₄, and the micro X package is ideal for low-cost, high-performance applications that require a surfacemount package.

`The LPD200MX is designed for commercial systems for use in low noise amplifiers and oscillators
operating over the RF and Microwave frequency ranges. The low noise figure makes it appopriate
for use in receivers in MMDS and GPS. This device is also suitable as a driver stage for WLAN and
ISM band spread spectrum applications.
