DESCRIPTION AND APPLICATIONS
The LP3000 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-write 0.25 µm by 3000 µm 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 LP3000 also features Si3N4 passivation and is available with plated source via-holes (LPV 3000) as an option for improved high-frequency performance. Also available in a ceramic flanged package (P100) and ball grid array package.
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 LPV 3000/LP 3000 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.
