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
m x 2250 m 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.

HANDLING PRECAUTIONS
To avoid damage to the devices care should be exercised during handling. Proper Electrostatic
Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and
testing. These devices should be treated as Class 1A (0-500 V). Further information on ESD control
measures can be found in MIL-STD-1686 and MIL-HDBK-263.
APPLICATIONS NOTES & DESIGN DATA
Applications Notes are available from your local Filtronic Sales Representative or directly from the
factory. Complete design data, including S-parameters, noise data, and large-signal models are
available on the Filtronic web site.
All information and specifications are subject to change without notice.
