NOTES:
1. 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. Power Dissipation defined as: P_T º (P_DC + P_IN) - P_OUT, where: P_DC = DC bias power, P_OUT = RF output power, and
P_IN = RF input power.
4. Power Dissipation to be de-rated as follows above 25°C:
          Absolute Maximum: P_T = 1.7W - (11mW/°C) x T_HS
          Recommended Continuous Operating: P_T = 1.4W - (11mW/°C) x T_HS
          where T_HS = heatsink or ambient temperature.
5. Specifications subject to change without notice.


Description

`The LP6872P100 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic
High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-write 0.25 mm by 720 mm 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 LP6872 also features Si₃N₄
passivation and is available in die form.

`Typical applications include commercial and military high-performance power amplifiers, including SATCOM uplink
transmitters, and medium-haul digital radio transmitters. Space level screening to FSS JANS grade is also available.
The LP6872-P100 may be procured in a variety of grades, depending upon specific user requirements. Standard lot
screening is patterned after MIL-STD-19500, JANC grade.
