DESCRIPTION AND APPLICATIONS
The LP750SOT89 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide
(AlGaAs/InGaAs) pseudomorphic High Electron Mobility Transistor (pHEMT). It utilizes a
0.25
m x 750
m Schottky barrier gate, defined by electron-beam photolithography. The recessed
"mushroom" gate structure minimizes parasitic gate-source and gate resistance. The epitaxial
structure and processing have been optimized for reliable high-power applications. The LP750 also
features Si3N4 passivation and is available in die form or in other packages.
Typical applications include drivers or output stages in PCS/Cellular amplifiers, WLL and WLAN
systems, and other types of wireless infrastructure systems.

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.
