(AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an
Schottky barrier gate. The recessed 鈥渕ushroom鈥?/div>
Ti/Pt/Au gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure
and processing have been optimized for optimum low noise performance. The LP7512鈥檚 active
areas are passivated with Si

, and the P70 ceramic package is ideal for low-cost, high-performance
applications that require a surface-mount package.
Typical applications include low noise receiver preamplifiers in wireless systems.
