FPD1500P100

¹TAmbient = 22°C unless otherwise noted ²Max. RF Input Limit must be further limited if input V_SWR > 2.5:1
³Users should avoid exceeding 80% of 2 or more Limits simultaneously
Notes:
• Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.
• Thermal Resitivity specification assumes a Au/Sn eutectic die attach onto a Au-plated copper heatsink or rib.
• 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 22°C:
                                                   P_TOT=3.2W (0.021W/°C) x T_HS
where THS = heatsink or ambient temperature above 22°C
(coefficient of de-rating formula is the Thermal Conductivity)
Example: For a 85°C heatsink temperature: P_TOT = 3.2W (0.021 x (85 22)) = 1.88W

The FPD1500P100 is a packaged AlGaAs/InGaAs pseudomorphic High Electron Mobility Transistor (PHEMT), featuring a 0.25 m by 1500 m Schottky barrier gate, defined by highresolution stepper-based photolithography. The recessed and offset Gate structure minimizes parasitics to optimize performance. The epitaxial structure and processing have been optimized for reliable high-power applications. The FPD1500P100 also features Si3N4 passivation and is also available in die form and in the low cost plastic SOT89 and DFN plastic packages.

FPD1500P100 applications include commercial and other narrowband and broadband high-performance amplifiers, including SATCOM uplink transmitters, PCS/Cellular low-voltage high-efficiency output amplifiers, and medium-haul digital radio transmitters.
