LP7612P70
•
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
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 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.
