DESCRIPTION AND APPLICATIONS The LPD200 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 SOT343 (also known as SC-70) package is ideal for low-cost, high-performance applications that require a surface-mount package. The LPD200SOT343 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 appropriate 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.

HANDLING PRECAUTIONS To avoid damage to the devices care should be exercised during handling. Proper Electrostatic Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and testing. These devices should be treated as Class 1A (0-500 V). Further information on ESD control measures can be found in MIL-STD-1686 and MIL-HDBK-263. APPLICATIONS NOTES & DESIGN DATA Applications Notes are available from your local Filtronic Sales Representative or directly from the factory. Complete design data, including S-parameters, noise data, and large-signal models are available on the Filtronic web site. PACKAGE OUTLINE
