MRF316

Overview

The MRF316 is an NPN silicon RF power transistor designed for wideband large-signal output amplifier stages in the 30–200 MHz frequency range. It features a built-in matching network for broadband operation and is guaranteed to deliver 80 W of output power with a minimum gain of 10 dB at 150 MHz and 28 Vdc. The device utilizes a gold metallization system for high reliability and is 100% tested for load mismatch at all phase angles with a 30:1 VSWR.

Feature Summary

• Gold metallization system for high reliability applications
• 100% tested for load mismatch at all phase angles with 30:1 VSWR

Applications

• Wideband large-signal output amplifier stages

Procurement Notes

Verify the specific package style against the official datasheet before procurement, as variations may exist within the product line. Confirm that the application environment does not involve medical or life-sustaining systems, as these uses are explicitly excluded by the manufacturer. Ensure proper thermal management is integrated into the design to maintain performance within the specified operating parameters.

Selection Notes

Select this component when designing amplifiers requiring consistent performance across the 30–200 MHz spectrum without external matching networks. The device is optimized for scenarios demanding high reliability under significant load mismatch conditions. Evaluate the 80 W output capability against the specific power requirements of the target amplifier stage to ensure adequate headroom.

Part Context

The MRF316 belongs to MACOM's RF Line of NPN silicon power transistors. This series is engineered specifically for robust performance in demanding radio frequency environments. The inclusion of internal matching components distinguishes it from discrete counterparts, simplifying circuit layout while maintaining signal integrity over a broad operational bandwidth.

Replacement Considerations

Consult the official MACOM documentation for verified substitute part numbers. Cross-referencing with similar models in the RF Line series is recommended to ensure compatibility with existing board layouts and thermal constraints.
