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 mm by 200 mm 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 Si3N4, 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.
