CDR6000

Overview

The CDR6000 is a dual-resonator bandpass ceramic filter manufactured by RFMi, designed for Global Navigation Satellite System (GNSS) applications. It operates with a center frequency of 1.223 GHz and features a bandwidth of 50 MHz. The component provides a nominal impedance of 50 Ohms and utilizes a nonstandard package configuration. This device serves as a critical filtering element in RF front-end circuits requiring precise signal selection within the L-band spectrum.

Feature Summary

• Dual-resonator bandpass architecture for enhanced selectivity
• Optimized for GNSS signal processing applications
• 50 Ohm impedance matching capability

Applications

• GNSS receiver front-end filtering
• L-band signal processing systems
• Satellite navigation equipment

Procurement Notes

Verify the specific datasheet version and manufacturing date code upon order confirmation. Confirm that the nonstandard package dimensions align with your PCB layout requirements. Ensure compatibility with your assembly process regarding the ceramic material properties. Cross-reference the part number with official RFMi documentation to confirm current production status and any potential obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a 1.223 GHz center frequency with 50 MHz bandwidth is required for GNSS applications. Consider the physical footprint constraints due to the nonstandard package size. Evaluate insertion loss and rejection specifications against system sensitivity requirements. Ensure the 50 Ohm impedance matches the surrounding RF circuitry to minimize signal reflection and maximize power transfer efficiency.
