LP7612P70
PACKAGED HIGH DYNAMIC RANGE PHEMT
• FEATURES
♦ 20 dBm Output Power at 1-dB Compression at 18 GHz
♦ 7.5 dB Power Gain at 18 GHz
♦ 16 dB Small Signal Gain at 2 GHz
♦ 0.8 dB Noise Figure at 2 GHz
• 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 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.
