• Engineered for Doherty-type multi-carrier power amplifier (MCPA) configurations
• Optimized for operation within the 1800 and 1900 MHz frequency bands
• Delivers high output power levels suitable for wireless base station transceivers

Applications

• Wireless base station transceivers
• Multi-carrier power amplifiers (MCPAs)
• Doherty-type power amplifier architectures

Procurement Notes

Verify the specific suffix 'SR6' against official NXP/Freescale documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the source document explicitly identifies this part number within the MRF8S18260H/S family to avoid confusion with similar variants. Cross-reference the manufacturer's current product status to confirm availability and lifecycle stage before procurement.

Selection Notes

Select this component when designing base station transceivers requiring high-efficiency amplification for multiple carriers in the 1800/1900 MHz spectrum. It is appropriate for systems utilizing Doherty topology to reduce size and component count compared to single-amplifier-per-carrier solutions. Verify thermal management requirements align with the device's high-output power capabilities.

Part Context

This transistor belongs to Freescale Semiconductor's RF LDMOS power transistor portfolio, specifically engineered for commercial wireless infrastructure. It represents a solution for increasing base station capacity without proportional increases in hardware footprint. The MRF8S18260H/S series provides industry-leading output levels for its designated frequency bands.

Replacement Considerations

Official substitutes include other members of the MRF8S18260H/S family, such as the MRF8P18265H/S or MRF8S19260H/S, provided they meet the specific frequency and power requirements of the design. Verify pinout compatibility and electrical specifications against the original schematic before substitution.
