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 µm by 3000 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 reliable high-power applications. The LP3000 also features Si3N4 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.

Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device. 2. Recommended Continuous Operating Limits should be observed for reliable device operation. 3.

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 280290°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.
