DESCRIPTION AND APPLICATIONS
The LP7612P70 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
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 LP7612's active areas are
passivated with Si
3
N
4
, and the P70 ceramic package is ideal for low-cost, high-performance
applications that require a surface-mount package.
Typical applications include high dynamic range receiver preamplifiers for commercial applications
including Cellular/PCS systems, WLAN and WLL systems, and other types of high-gain
applications for radio link systems.

This PHEMT is susceptible to damage from Electrostatic Discharge. Proper precautions should be used when handling these
devices.
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.
