  • FEATURES ♦ 33.5 dBm Output Power at 1-dB Compression at 18 GHz ♦ 7 dB Power Gain at 18 GHz ♦ 30.5 dBm Output Power at 1-dB Compression at 3.3V ♦ 45% Power-Added Efficiency
  • 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 is also available in a P100 flanged ceramic package and in the low cost plastic SOT89 package. Typical applications include commercial and other high-performance power amplifiers.

  • ABSOLUTE MAXIMUM RATINGS Parameter Symbol Test Conditions Min Max Units Drain-Source Voltage V DS T Ambient = 22 ± 3 °C 12 V Gate-Source Voltage V GS T Ambient = 22 ± 3 °C -5 V Drain-Source Current I DS T Ambient = 22 ± 3 °C 2xI DSS mA Gate Current I G T Ambient = 22 ± 3 °C 30 mA RF Input Power P IN T Ambient = 22 ± 3 °C 1.2 W Channel Operating Temperature T CH T Ambient = 22 ± 3 °C 175 ºC Storage Temperature T STG — -65 175 ºC Total Power Dissipation P TOT T Ambient = 22 ± 3 °C 6.0 W Notes:
  • Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.
  • Power Dissipation defined as: P TOT ≡ (P DC + P IN ) – P OUT , where P DC : DC Bias Power P IN : RF Input Power P OUT : RF Output Power
  • Absolute Maximum Power Dissipation to be de-rated as follows above 25 °C: P TOT = 6.0W – (0.040W/ °C) x T HS where T HS = 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.
