CDR2008

Overview

The RFMi CDR2008 is a double resonator ceramic bandpass filter designed for sub-6GHz and fifth-generation wireless applications. It operates with a center frequency of 3570 MHz and provides a bandwidth of 100 MHz. The component features a nominal impedance of 50 Ohms and an insertion loss of 1.5 dB. Its physical dimensions are 15.9 mm by 6.3 mm by 4.4 mm, suitable for compact RF front-end modules in modern communication systems.

Feature Summary

• Double resonator ceramic construction for stable performance
• Optimized for sub-6GHz and 5G wireless environments
• Standard 50 Ohm impedance matching

Applications

• Sub-6GHz cellular infrastructure
• 5G small cell deployments
• RF front-end modules for wireless communications

Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and thermal characteristics. Ensure compatibility with existing PCB footprints measuring 15.9x6.3x4.4 mm. Confirm RoHS compliance status through official manufacturer documentation before integration into final assemblies.

Selection Notes

Select this component when designing for the 3.57 GHz band within sub-6GHz spectrum requirements. The 100 MHz bandwidth supports standard channel allocations in 5G networks. Consider the 1.5 dB insertion loss impact on system noise figure during link budget calculations.

Part Context

RFMi, now part of Akoustis Technologies, specializes in SAW, crystal, and ceramic RF components. The CDR2008 belongs to their ceramic filter portfolio, targeting high-performance applications in WiFi, LTE, and 5G sectors. These filters provide reliable signal selection for digital and wireless communication subsystems.

Replacement Considerations

Consult official substitution lists for equivalent double resonator ceramic filters. Verify that alternative parts match the 3570 MHz center frequency, 100 MHz bandwidth, and 50 Ohm impedance specifications exactly.
