It features SMA female connectors and operates with a center frequency of 4 GHz and a passband bandwidth of 25 MHz. The component maintains a characteristic impedance of 50 ohms and includes four internal sections to achieve the specified filtering characteristics. It functions within an operating temperature range of -20°C to 60°C.

Feature Summary

• Four-section bandpass filter design
• SMA female connector interface
• 50-ohm system impedance

Applications

• Test and measurement instrumentation
• Laboratory instrumentation systems
• Antenna testing setups

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the SMA connector gender matches your system requirements. Ensure the operating temperature range meets your environmental conditions. Check for any recent revisions to the electrical specifications in the official Pasternack documentation before finalizing integration.

Selection Notes

Select this model when a precise 4 GHz center frequency with narrow 25 MHz bandwidth is required. The four-section architecture provides steep roll-off characteristics suitable for rejecting adjacent channel interference. Consider the physical size and weight constraints, as the unit weighs approximately 49 grams. Verify compatibility with existing SMA-based infrastructure.

Part Context

This component belongs to the Pasternack RF Coaxial Filters series, specifically categorized under Signal Conditioning products. It is part of a family of filters utilizing SMA interfaces, distinct from broader microwave assembly categories. The product line focuses on providing standardized filtering solutions for radio frequency applications requiring reliable performance in laboratory and field environments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify exact electrical parameters, including center frequency and bandwidth, when evaluating alternative components from other manufacturers or different Pasternack models.
