Overview
The Murata DFCH31G64HDJAA-RF1 is a SAW duplexer designed for signal conditioning applications. It operates within a frequency range of 2400MHz to 5950MHz with a center frequency of 6610MHz. The component features a nominal impedance of 50 Ohms and supports a maximum power capacity of 1W. It is housed in an 8-SMD, No Lead package suitable for board mounting. The device functions reliably across an operating temperature range from -30°C to +85°C.
Feature Summary
- Constructed using copper conductors and ceramic materials for high-frequency performance
- Designed as a chip multilayer hybrid balun for efficient signal processing
- Integrated into the Gigafil series for specialized RF filtering
Applications
- Wireless communication systems requiring signal conditioning
- RF front-end modules operating in the 2.4GHz to 6GHz bands
- High-frequency circuit designs utilizing SAW duplexers
Procurement Notes
Verify the specific suffix and revision level against official Murata documentation to ensure compatibility with your design requirements. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure that the 8-SMD no-lead package dimensions align with your PCB footprint specifications before finalizing procurement decisions.
Selection Notes
Select this component when a SAW duplexer with a 50 Ohm impedance is required for frequencies up to 5950MHz. Consider the thermal operating limits of -30°C to +85°C for environmental suitability. Evaluate the 1W power handling capability against system transmission requirements. Ensure the board-mount package style fits the assembly constraints.
Part Context
This part belongs to the Murata Gigafil series, which specializes in RF filters and duplexers. The DFCH series typically addresses signal conditioning needs in modern wireless infrastructure. These components are engineered to provide precise frequency selection and interference rejection in compact form factors suitable for dense electronic assemblies.
Replacement Considerations
Consult official Murata substitution guides for verified alternatives. Cross-reference electrical parameters such as center frequency and impedance when evaluating potential substitutes to maintain system integrity.
