MAGX-001214-500L0S

Overview

The MAGX-001214-500L0S is a gold-metalized Gallium Nitride (GaN) on Silicon Carbide (SiC) RF power transistor optimized for pulsed L-Band radar applications. It operates within the 1200 MHz to 1400 MHz frequency range with a typical drain voltage of +50 V. The device delivers a peak output power of 500 W under standard conditions (300 µs pulse, 10% duty cycle), achieving a typical power gain of 19.2 dB and a drain efficiency of 56%. Under extended pulse conditions (1.0 ms pulse, 10% duty cycle at 42 V), it provides 375 W peak output power with 55% efficiency. The component features internally matched input and output networks in a common-source configuration.

Applications

• L-Band pulsed radar systems

Procurement Notes

Verify the specific ordering suffix 'L0S' corresponds to the flangeless package variant when sourcing. Confirm that the procurement channel accepts components from M/A-COM Technology Solutions Inc. or its affiliates. Ensure handling procedures account for the specified ESD sensitivity ratings during installation. Check for any recent product change notices regarding manufacturing updates.

Selection Notes

Select this component for designs requiring high peak power density in the L-Band spectrum. The internal matching reduces external component count and simplifies impedance transformation networks. Consider thermal management requirements carefully, as junction temperature directly impacts mean time to failure. Evaluate load mismatch stability specifications against the intended antenna system VSWR characteristics.

Part Context

This part belongs to the MAGX series of GaN on SiC transistors designed for demanding RF power applications. The 'L0S' suffix specifically denotes the flangeless package version, distinct from the flanged 'L00' variant. These devices are engineered to provide high gain, efficiency, and bandwidth for modern radar architectures.

Replacement Considerations

The datasheet lists MAGX-001214-500L00 as the flanged equivalent. No other direct substitute part numbers are documented in the provided source material.

FAQ

What is the difference between the MAGX-001214-500L00 and MAGX-001214-500L0S?

The primary difference is the package style; the MAGX-001214-500L00 features a flanged package, while the MAGX-001214-500L0S is flangeless.

How does the device handle load mismatch conditions?

The transistor is designed to operate reliably under extreme mismatch load conditions, supporting a load mismatch stability VSWR of 3:1 and a load mismatch tolerance VSWR of 5:1 at peak power.

What are the recommended device sequencing procedures?

To turn the device ON, set VGS to pinch-off, apply VDS, increase VGS to reach IDS current, then apply RF power. To turn OFF, remove RF power, decrease VGS to pinch-off, then decrease VDS to 0 V.
