MRF455MP

Overview

The MRF455MP is a matched pair of silicon bipolar RF transistors manufactured by MACOM Technology Solutions. Designed for high-performance applications, this component operates within the 2700 MHz to 2900 MHz frequency range. It delivers a saturated output power of 24 dBm with a gain of 12 dB. The device requires a bias voltage of 12.5 V and supports a maximum dissipation of 60 W per transistor in the matched configuration. It utilizes a flange ceramic package suitable for robust mounting. Key electrical characteristics include reverse isolation greater than 30 dB, and both input and output return losses exceeding 15 dB.

• Matched pair configuration ensures balanced performance for differential amplifier designs
• High reliability construction using full gold metallization processes
• Optimized for linear and saturated operation in demanding RF environments

Applications

• Avionics systems
• Military radio communications
• Radar systems
• Industrial, scientific, and medical (ISM) equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and thermal specifications. Ensure that the procurement channel provides original manufacturer documentation to validate authenticity. Confirm that the received components match the exact part number designation without unauthorized modifications or generic substitutions.

Selection Notes

Select the MRF455MP when a matched pair topology is required for balanced RF signal processing. This component is appropriate for designs operating between 2.7 GHz and 2.9 GHz requiring moderate power output. Consider the flange ceramic package for thermal management needs. Evaluate the 12.5 V bias requirement against available power supply constraints in the target system architecture.

Part Context

The MRF455MP belongs to the MACOM MRF series of silicon bipolar transistors. This series covers frequencies from DC to 3.5 GHz and includes various discrete devices and matched pairs. The MRF455 variant serves as the base component, with the MP suffix indicating the matched pair configuration. These devices are engineered for high performance and long-term reliability in critical electronic applications.

Replacement Considerations

Publicly confirmed substitute part numbers for the MRF455MP are not available in verified sources. Designers should consult MACOM directly for qualified alternatives or verify if other MRF series matched pairs meet the specific electrical requirements.
