DESCRIPTION AND APPLICATIONS
The FPD1500SOT89 is a packaged depletion mode AlGaAs/InGaAs pseudomorphic High Electron
Mobility Transistor (pHEMT). It utilizes a 0.25 x 1500
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 FPD1500 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.
