Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement. Confirm that the SMA female connector type and bidirectional threaded mounting requirements match your system design. Ensure environmental temperature ratings align with operational conditions. Cross-reference datasheet specifications for insertion loss and rejection values to guarantee compatibility with specific RF circuit requirements.

Selection Notes

Select this component when a narrow 3.5 GHz passband is required within the 27.5 GHz to 31 GHz spectrum. The nine-section architecture offers steep skirt characteristics suitable for interference suppression. Verify that the SMA interface and threaded mounting style are compatible with existing chassis or panel layouts. Consider the 2.5 dB insertion loss impact on overall system gain budget during integration planning.

Part Context

This component belongs to Pasternack's RF filter portfolio, specifically designed for high-frequency applications. It utilizes a multi-section topology to achieve precise frequency selection. The product is distinct from cable assemblies or passive interconnects often listed under similar prefixes. It serves as a dedicated signal conditioning element for microwave systems requiring defined spectral boundaries.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with any alternative filters regarding mechanical dimensions, connector types, and electrical performance curves before substitution.
