CDR5000

Overview

The CDR5000 is a 5.825 GHz bandpass ceramic filter designed for Dedicated Short Range Communications (DSRC) applications. It features a center frequency of 5.825 GHz with a bandwidth of 200 MHz and operates at a standard impedance of 50 ohms. The component utilizes a nonstandard package configuration suitable for surface mount integration.

Feature Summary

• Engineered specifically for DSRC signal processing requirements
• Utilizes ceramic dielectric technology for stable RF performance
• Provides precise bandpass filtering characteristics

Applications

• Dedicated Short Range Communications systems
• RF front-end filtering modules
• Automotive communication interfaces

Procurement Notes

Verify the specific datasheet revision, as multiple PDF versions exist in public repositories. Confirm the exact physical dimensions against your PCB footprint due to the nonstandard package designation. Ensure compatibility with the specified 50-ohm system impedance before finalizing procurement orders.

Selection Notes

Select this component when designing for the 5.825 GHz ISM band used in DSRC standards. The fixed 200 MHz bandwidth dictates its suitability for specific channel allocations. Consider the nonstandard package size during layout planning to ensure adequate clearance and soldering access.

Part Context

This part belongs to the RFMi ceramic filter series, which focuses on high-frequency signal conditioning. Unlike general-purpose filters, these components are optimized for specific communication bands. The CDR5000 represents a specialized solution for short-range vehicular data exchange protocols.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical equivalence carefully if considering alternative manufacturers, particularly regarding the 5.825 GHz center frequency and 200 MHz bandwidth specifications.
