MAGX-001214-500L00

Overview

The MAGX-001214-500L00 is a gold-metalized Gallium Nitride (GaN) on Silicon Carbide (SiC) RF power transistor optimized for pulsed L-Band radar applications. It delivers 500 W peak output power within the 1200-1400 MHz frequency range using a 300 μs pulse width and 10% duty cycle at VDD = 50 V. The device features internally matched broadband Class AB operation with typical drain efficiency of 56% and power gain of 19.2 dB. It supports extended pulse conditions up to 1.0 ms at reduced voltage.

Feature Summary

• Utilizes GaN on SiC depletion-mode HEMT technology for high ruggedness and breakdown voltage tolerance under extreme mismatch load conditions.
• Features internal matching networks enabling direct integration into broadband Class AB amplifier circuits without external impedance transformation components.
• Provides high thermal stability and reliability, characterized by an estimated mean time to failure of 600 years when channel temperature remains below 200°C.

Applications

• L-Band pulsed radar systems
• High-power radio frequency amplification
• Military communication transmitters

Procurement Notes

Verify the specific package variant required for the design; the MAGX-001214-500L00 denotes the flanged configuration, while MAGX-001214-500L0S indicates the flangeless version. Confirm that the application environment adheres to the specified absolute maximum ratings, particularly regarding junction temperature limits and correct device sequencing during power-up and power-down cycles to ensure long-term operational integrity.

Selection Notes

Select this component for designs requiring high peak power density in the L-Band spectrum. Ensure the thermal management system can maintain the junction temperature below 200°C to preserve the rated MTTF. Verify that the drive circuitry can supply the necessary input power levels and that the bias sequencing follows the manufacturer's recommended protocol to prevent device damage during transient states.

FAQ

What is the recommended device sequencing for turning the MAGX-001214-500L00 ON?

First set VGS to the pinch-off voltage (typically -5 V), then turn on VDS to the nominal voltage (50 V). Next, increase VGS until the desired IDS current is reached, and finally apply the RF power to the desired level.

How does the device handle load mismatch conditions?

The transistor exhibits high ruggedness and stable operation under extreme mismatch loads. It maintains stability with a VSWR-S of 3:1 and demonstrates tolerance up to a VSWR-T of 5:1 at 500 W peak output power.

What are the electrical specifications for extended pulse width conditions?

Under extended pulse conditions of 1.0 ms pulse width and 10% duty cycle at VDD = 42 V, the device typically delivers 375 W peak output power with 18.5 dB power gain and 55% drain efficiency.
