ESCRIPTION
:
The FPD2250SOT89 is a packaged depletion
mode AlGaAs/InGaAs pseudomorphic High
Electron Mobility Transistor (pHEMT). It
utilizes a 0.25 µm x 2250 µm Schottky barrier
gate, defined by high-resolution stepper-based
photolithography. The double recessed gate
structure minimizes parasitics to optimize
performance, with an epitaxial structure
designed for improved linearity over a range of
bias conditions and i/p power levels.
