The FPD750SOT89CE is a packaged depletion mode AlGaAs/InGaAs pseudomor-
phic High Electron Mobility Transistor (pHEMT). It features a 0.25μmx1500μm
Schottky barrier gate, defined by high-resolution stepper-based photolithography.
The double recessed gate structure minimizes parasitics to optimize performance.
The epitaxial structure is designed for improved linearity over a range of bias condi-
tions and input power levels.
