Overview
The MRF454 is an NPN silicon RF power transistor designed for power amplifier applications in industrial, commercial, and amateur radio equipment up to 30 MHz. Specified at 12.5 V and 30 MHz, it delivers a minimum output power of 80 W with a minimum gain of 12 dB and an efficiency of 50%. The device utilizes the CASE 211–11, STYLE 1 package.
Feature Summary
- NPN silicon construction optimized for high-power RF amplification
- Designed for linear operation in industrial and commercial radio systems
- Capable of sustaining specified performance at 12.5 V supply voltage
Applications
- Industrial radio equipment power amplifiers
- Commercial communication system transmitters
- Amateur radio station power amplifiers
Procurement Notes
Verify the specific revision status (e.g., Rev. V1) against current MACOM documentation before procurement. Confirm that the CASE 211–11, STYLE 1 mechanical dimensions match the target PCB or chassis mounting requirements. Ensure the application environment supports the thermal management necessary for 80 W output power dissipation.
Selection Notes
Select this component when designing linear amplifiers operating below 30 MHz requiring 80 W output at 12.5 V. It serves as a direct replacement for legacy designs specifying similar NPN silicon RF power transistors in the 211-11 footprint. Evaluate thermal resistance capabilities to maintain junction temperature within safe operating limits during continuous wave operation.
Part Context
The MRF454 belongs to MACOM's RF Line of NPN silicon power transistors. This series targets VHF band applications where high linearity and power handling are required. It complements other devices in the portfolio by offering a standardized 211-11 form factor for easy integration into existing amplifier architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult MACOM technical support for equivalent components if the MRF454 is unavailable, ensuring pinout and thermal characteristics remain compatible.
