DESCRIPTION AND APPLICATIONS
The LP1500SOT89 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide
(AlGaAs/InGaAs) pseudomorphic High Electron Mobility Transistor (pHEMT). It utilizes a
0.25 µm x 1500 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 LP1500 also
features Si3N4 passivation and is available in die form or in other packages.
Typical applications include drivers or output stages in PCS/Cellular amplifiers, WLL and WLAN
systems, and other types of wireless infrastructure systems.

Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.
Power Dissipation defined as: PTOT ≡ (PDC + PIN) – POUT, where
PDC: DC Bias Power
PIN: RF Input Power
POUT: RF Output Power
Absolute Maximum Power Dissipation to be de-rated as follows above 25°C:
PTOT= 2.3W – (0.015W/°C) x TPACK
where TPACK = source tab lead temperature
This PHEMT is susceptible to damage from Electrostatic Discharge. Proper precautions should be used when handling these

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.
