• Provides excellent out-of-band rejection characteristics
• Utilizes Surface Acoustic Wave (SAW) technology

Applications

• Test equipment signal conditioning
• General laboratory use
• Low-cost RF power monitoring

Procurement Notes

Verify the specific part number CBPFS-0902 against official Crystek documentation to confirm the 902.5 MHz center frequency and 25 MHz bandwidth specifications. Ensure compatibility with 50 ohm systems and SMA connector requirements. Confirm that the -40°C to +85°C temperature rating meets the operational environment needs. Cross-reference datasheets to validate physical dimensions and mounting style before procurement.

Selection Notes

Select this component when a SAW-based band pass filter is required for the 902.5 MHz ISM band. The choice is driven by the need for high out-of-band rejection and a robust SMA connectorized form factor. Consider the inline design and specific bandwidth of 25 MHz for applications demanding precise frequency selection in test or lab environments.

Part Context

This component belongs to the CBPFS series of SAW band pass filters from Crystek Corporation. The series shares common design traits, including rugged SMA housings and wide temperature ranges. Variants within the series differ primarily in center frequency and pass bandwidth, such as the CBPFS-0915 for 915 MHz applications.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Evaluate other CBPFS series models like CBPFS-0915 if frequency adjustments are permissible. Verify mechanical and electrical compatibility with any alternative SAW filters from different manufacturers.
