DESCRIPTION AND APPLICATIONS
The LP750 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs)
Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-
write 0.25
µ
m by 750
µ
m Schottky barrier gate. The recessed “mushroom” gate structure minimizes
parasitic gate-source and gate resistances. The epitaxial structure and processing have been
optimized for reliable high-power applications. The LP750 also features Si
3
N
4
passivation and is
available in a variety of packages, including SOT89 and P100 packages.
Typical applications include commercial and other types of high-performance power amplifiers,
including use within SATCOM uplink transmitters, PCS/Cellular low-voltage high-efficiency output
amplifiers, and medium-haul digital radio transmitters.
