CDR2012

Overview

The RFMi CDR2012 is a ceramic bandpass filter designed for sub-6GHz and 5th generation wireless applications. It features a center frequency of 3.25 GHz with a bandwidth of 300 MHz, operating at a standard impedance of 50 Ohms. The component utilizes a surface-mount package with dimensions of 7.40mm x 4.62mm (0.291" L x 0.182" W). This device is currently active in production and is available in bag packaging.

Feature Summary

• Ceramic construction for stable RF filtering performance
• Surface-mount design for automated assembly integration
• Optimized for sub-6GHz and 5G communication bands

Applications

• Sub-6GHz wireless infrastructure
• 5G mobile network components
• RF front-end modules requiring bandpass filtering

Procurement Notes

Verify the specific datasheet version to confirm exact insertion loss and rejection specifications, as these values are critical for system compliance. Ensure the supplier provides RoHS compliance documentation, as indicated by general product listings. Confirm that the bag packaging meets your handling requirements before finalizing orders.

Selection Notes

Select this component when a fixed 3.25 GHz center frequency with 300 MHz bandwidth is required for sub-6GHz applications. The 50 Ohm impedance matches standard RF transmission lines. Consider the 7.40mm x 4.62mm footprint for PCB layout constraints. Verify thermal and mechanical stability requirements against the ceramic material properties.

Part Context

RFMi, an Akoustis brand, specializes in RF components using SAW, crystal, and ceramic technologies. The CDR series represents their ceramic filter line, targeting digital and wireless communications.
