MAGX-000912-500L00

Overview

The MAGX-000912-500L00 is a gold metalized Gallium Nitride (GaN) on Silicon Carbide (SiC) RF power transistor optimized for pulsed avionics and radar applications. It delivers 500 W peak output power within the 960 to 1215 MHz frequency range using a 128 μs pulse width and 10% duty cycle. The device features internally matched common-source configuration, +50 V typical operation, and high breakdown voltage for stable performance under extreme mismatch load conditions.

Feature Summary

• Utilizes GaN on SiC depletion-mode HEMT technology for high gain, efficiency, and ruggedness.
• Features an internally matched common-source configuration supporting broadband Class AB operation.
• Provides high breakdown voltages ensuring reliable and stable operation under extreme mismatch load conditions.

Applications

• Civilian Air Traffic Control (ATC), L-Band Secondary Radar for IFF and Mode-S Avionics
• Military radar for IFF and Data Links

Procurement Notes

Verify the specific package variant required for the design; the MAGX-000912-500L00 denotes the flanged version, while the MAGX-000912-500L0S indicates the flangeless version. Confirm RoHS compliance and 260 °C reflow compatibility requirements with the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing pulsed power amplifiers requiring 500 W peak output in the 960 to 1215 MHz band. Ensure the system supports a +50 V drain supply and can manage the thermal resistance of 0.2 °C/W. Verify that the application environment maintains junction temperatures below 200 °C to achieve the specified 600-year MTTF rating.
