Description

`The LPV1500 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High
Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-write 0.25 m by 1500 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 LP1V500 also features Si₃N₄ passivation and is available in a flanged ceramic package (P100). The LPV1500 features plated source thru-vias for improved
performance.

`Typical applications include commercial and military high-performance power amplifiers, including SATCOM uplink
transmitters, PCS/Cellular low-voltage high-efficiency output amplifiers, and medium-haul digital radio transmitters. The LP1500 may be procured in a variety of grades, depending upon specific user requirements. Standard lot screening is
patterned after MIL-STD-19500, JANC grade. Space-level screening to FSS JANS grade is also available.
