MRF1004MB

Overview

The MRF1004MB is a microwave pulse power silicon NPN transistor manufactured by MACOM Technology Solutions. It operates within the 960–1215 MHz frequency range and is designed for Class B and C common base amplifier applications. The device guarantees an output power of 4.0 W peak at 1090 MHz with a minimum gain of 10 dB when driven at 35 Vdc. It features internal input matching for broadband operation, nitride passivation, and gold metallization with emitter ballasting to ensure long life and resistance to metal migration.

Feature Summary

• Designed for short and long pulse TACAN, IFF, DME, and radar transmitter applications
• Guaranteed performance tested for load mismatch at all phase angles with 10:1 VSWR
• Internal input matching provides broadband operational capability
• Gold metallized structure with emitter ballasting for enhanced reliability

Applications

• TACAN transmitters
• IFF (Identification Friend or Foe) systems
• DME (Distance Measuring Equipment) transmitters
• Radar transmitters

Procurement Notes

Verify the specific datasheet revision against the manufacturer's official documentation before procurement. Confirm that the package style matches the required mechanical constraints for the target application. Ensure compatibility with the intended biasing conditions and thermal management requirements for pulse power operations.

Selection Notes

Select this component for high-reliability microwave pulse power applications requiring guaranteed performance under load mismatch conditions. Consider the industry standard package form factor for integration into existing transmitter designs. Evaluate the need for internal input matching to simplify circuit design for broadband operations.

Part Context

The MRF1004MB belongs to the family of microwave pulse power silicon NPN transistors produced by MACOM. It shares functional similarities with other models in the series but is specifically characterized for the 960–1215 MHz band. The device utilizes a CASE 332A-03, Style 1 package, which is an industry-standard form factor for this class of RF power components.

Replacement Considerations

Cross-reference with MRF1004 and MRF1004MA for potential substitution options. Verify electrical specifications and package compatibility before replacing the original component.
