DESCRIPTION AND APPLICATIONS
The LP3000 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High Electron
Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-write 0.25
m by 3000
m Schottky barrier gate. The
recessed "mushroom" gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure and
processing have been optimized for reliable high-power applications. The LP3000 also features Si

N
4
passivation and is
available with plated source via-holes (LPV 3000) as an option for improved high-frequency performance. Also available in
a ceramic flanged package (P100) and ball grid array package.
Typical applications include commercial and military high-performance power amplifiers, including SATCOM uplink
transmitters, PCS/Cellular low-voltage high-efficiency output amplifiers, and medium-haul digital radio transmitters. The
LPV 3000/LP 3000 may be procured in a variety of grades, depending upon specific user requirements. Standard lot
screening is patterned after MIL-STD-19500, JANC grade. Space-level screening to FSS JANS grade is also available.

HANDLING PRECAUTIONS:
PHEMT chips should be stored in a dry nitrogen environment until assembly. Care should be exercised during handling to
avoid damage to the devices. 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 (0-500V), and 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 1 min. 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.
APPLICATIONS NOTES AND DESIGN DATA:
Applications Notes are available from your local FSS Sales Representative, or directly from the factory. Complete design
data, including S-parameters, Noise data, and Large-Signal models, is available on 3.5" diskette, or may be down-loaded
from our Web Page.
