0912GN-15E

Overview

The Microchip Technology 0912GN-15E is a Gallium Nitride (GaN) transistor designed for E Class driver applications. It operates within the 960-1215 MHz frequency range and delivers a pulsed output power of 15 Watts under 128us, 10% duty cycle conditions. The device requires a 50V drain-source bias voltage and features common source architecture with Class AB operation. Key electrical characteristics include a typical power gain of 18.1 dB, drain efficiency exceeding 60%, and excellent gain flatness of 0.2 dB. Maximum ratings specify a drain-source voltage of 150 V and an operating junction temperature up to +200°C.

Feature Summary

• Excellent gain flatness of 0.2 dB across the operational bandwidth
• Robust construction using gold metallization and eutectic die attach for high reliability
• Compact footprint available in multiple package options including 55-QQ and 55-QQP

Applications

• IFF (Identification Friend or Foe) systems
• Mode-S transponders
• DME (Distance Measuring Equipment)
• TACAN (Tactical Air Navigation)
• TCAS (Traffic Collision Avoidance System)

Procurement Notes

Verify the specific package variant required, as the base model number corresponds to three distinct physical footprints: 55-QQ, 55-QQP, and 55-78029. Confirm that the ordering suffix matches the desired case outline dimensions. Ensure compatibility with 50Ω input and output impedances for standard plug-and-play pallet integration. Validate thermal management requirements against the maximum junction temperature rating of +200°C during system design.

Selection Notes

Select this component for avionics applications requiring high linearity and wideband performance in the 960-1215 MHz spectrum. The device is optimized for pulsed operations with a 128us pulse width and 10% duty cycle. Consider the specific package size constraints when choosing between the compact 55-QQ/QLP options and the larger 55-78029 pallet. Ensure the driving circuit can provide the necessary 50V bias and appropriate gate voltage levels for Class AB operation.
