FEATURES
25 dBm Output Power at 1-dB
Compression at 18 GHz
9.5 dB Power Gain at 18 GHz
55% Power-Added Efficiency
DESCRIPTION AND APPLICATIONS
The LP6836 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 360
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 high dynamic range. The LP6836 also features Si
3
N
4
passivation and is available in
P70 and SOT343 package types.
Typical applications include high dynamic range driver stages for commercial applications including
wireless infrastructure systems and broad bandwidth amplifiers.

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.
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.
