DIE SIZE: 18.0X13.0 mils (460x330 µm)
DIE THICKNESS: 3.9 mils (100 µm)
BONDING PADS: 1.9X1.9 mils (50x50 µm)
DESCRIPTION AND APPLICATIONS
The LP7612 is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs)
Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam directwrite 0.25 µm by 200 µm 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 LP7612 also features Si3 N4 passivation and is available in a
P70 ceramic package.
Typical applications include high dynamic range receiver preamplifiers for commercial applications
including Cellular/PCS systems, WLL and WLAN systems, and broadband amplifiers.

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= 500mW – (3.3mW/°C) x THS
where THS = heatsink or ambient temperature.
•
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.
