CDR2002

Overview

The RFMi CDR2002 is a ceramic band-pass filter designed for radio frequency applications. It features a center frequency of 3.45 GHz and a bandwidth of 100 MHz. The component operates with a standard impedance of 50 Ohms. This monoblock device is constructed using ceramic technology to provide reliable signal filtering in wireless communication systems.

Feature Summary

• Monoblock ceramic construction for structural integrity
• Band-pass filtering capability centered at 3.45 GHz
• Standard 50 Ohm impedance matching

Applications

• Sub-6G wireless communication systems
• Fifth generation (5G) network infrastructure
• Radio frequency front-end modules

Procurement Notes

Verify the specific datasheet version from RFMi or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm RoHS compliance status if required by regional regulations before finalizing procurement orders.

Selection Notes

Select this component when a narrow 100 MHz bandwidth is required around the 3.45 GHz frequency point. Compare against similar models like the CDR2001, which offers a wider 300 MHz bandwidth, to determine if the tighter filtering of the CDR2002 meets specific spectral mask requirements for the target application.

Part Context

RFMi, an Akoustis brand, specializes in RF components utilizing SAW, crystal, and ceramic technologies. The CDR2002 belongs to their ceramic filter portfolio, designed for digital and wireless applications. These filters serve as critical frequency control elements in transmitters and receivers within modern communication devices.

Replacement Considerations

The RFMi CDR2001 is a related band-pass filter model. While it shares the same 3450 MHz center frequency, it offers a 300 MHz bandwidth compared to the CDR2002's 100 MHz. Verify if the wider bandwidth of the CDR2001 is acceptable for the specific application requirements.
