DESCRIPTION AND APPLICATIONS
The FPD750SOT343 is a packaged depletion mode AlGaAs/InGaAs pseudomorphic High Electron
Mobility Transistor (pHEMT). It utilizes a 0.25
μm
x 750
μm
Schottky barrier Gate, defined by
high-resolution stepper-based photolithography. The recessed and offset Gate structure minimizes
parasitics to optimize performance, with an epitaxial structure designed for improved linearity over a
range of bias conditions and input power levels. The FPD750 is available in die form and in other
packages.
Typical applications include drivers or output stages in PCS/Cellular base station high-intercept-
point LNAs, WLL and WLAN systems, and other types of wireless infrastructure systems.
