DESCRIPTION AND APPLICATIONS
The FPD2250 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility Transistor (PHEMT),
featuring a 0.25
碌m
by 2250
碌m
Schottky barrier gate, defined by high-resolution stepper-based
photolithography. The recessed and offset Gate structure minimizes parasitics to optimize
performance. The epitaxial structure and processing have been optimized for reliable high-power
applications. The FPD2250 also features Si

passivation and is available in a P100 flanged
ceramic package and in the low cost plastic SOT89 plastic package.
Typical applications include commercial and other narrowband and broadband high-performance
amplifiers, including SATCOM uplink transmitters, PCS/Cellular low-voltage high-efficiency output
amplifiers, and medium-haul digital radio transmitters.
