DESCRIPTION AND APPLICATIONS
The FP2250QFN is a high performance, leadless, encapsulated packaged Aluminum Gallium
Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) pseudomorphic High Electron Mobility
Transistor (pHEMT). It utilizes a 0.25
µm
x 2250
µm
Schottky barrier gate, defined by electron-
beam photolithography. The recessed “mushroom” gate structure minimizes parasitic gate-source
and gate resistance. The epitaxial structure and processing have been optimized for reliable high-
power applications. The FP2250’s active areas are passivated with Si
3
N
4
, and the QFN package is
ideal for low-cost, high-performance applications that require a surface-mount package. Typical
applications include drivers or output stages in PCS/Cellular amplifiers, WLL and WLAN systems,
and other types of wireless infrastructure systems up to 10 GHz.
