Procurement Notes
Verify the current manufacturing status as this specific part number may be discontinued or subject to change. Confirm compatibility with your RF circuit requirements by reviewing the latest official datasheet from Murata Electronics. Ensure that the 50-ohm impedance and frequency specifications align with your system design before procurement.
Selection Notes
Select this component for applications requiring a SAW duplexer with a center frequency near 6610 MHz. Consider its 1W power handling capability and 50-ohm impedance match. Evaluate the 7-terminal SMD package size against your board layout constraints. Verify AEC-Q200 or other relevant certifications if used in automotive or industrial environments.
Part Context
This device belongs to Murata's line of RF signal conditioning components, specifically SAW filters and duplexers. These components are engineered for high-performance wireless applications, offering reliable frequency selection and interference rejection in compact form factors suitable for modern electronic devices.
Replacement Considerations
Check for direct substitutes listed in Murata's obsolescence notices. Generic replacements may not match the precise 6610 MHz center frequency or 2400-5950 MHz bandwidth. Validate any alternative part's impedance and power ratings against the original specifications.
