DESCRIPTION AND APPLICATIONS
The FPD3000 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility Transistor (PHEMT),
featuring a 0.25
m by 3000 m Schottky barrier gate, defined by high-resolution stepper-based
photolithography. The recessed and offset Gate structure minimizes parasitics to optimize
performance. The epitaxial structure and processing have been optimized for reliable high-power
applications. The FPD3000 also features Si

4
passivation and is available in a P100 flanged
ceramic package and in the low cost plastic SOT89 plastic package.
Typical applications include commercial and other narrowband and broadband high-performance
amplifiers, including SATCOM uplink transmitters, PCS/Cellular low-voltage high-efficiency output
amplifiers, and medium-haul digital radio transmitters.

Notes:
Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.

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 per ESD-STM5.1-1998, Human Body Model.
Further information on ESD control measures can be found in MIL-STD-1686 and MIL-HDBK-263.
ASSEMBLY INSTRUCTIONS
The recommended die attach is gold/tin eutectic solder under a nitrogen atmosphere. Stage
temperature should be 280-290
C; maximum time at temperature is one minute. The recommended
wire bond method is thermo-compression wedge bonding with 0.7 or 1.0 mil (0.018 or 0.025 mm)
gold wire. Stage temperature should be 250-260
C.
