GENERAL DESCRIPTION:
The FPD1500DFN 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.
TYPICAL APPLICATIONS:
•
Drivers or output stages in PCS/Cellular
base station transmitter amplifiers
High intercept-point LNAs
•
•
WLL and WLAN systems, and other types
of wireless infrastructure systems.
