CDR3002

Overview

The CDR3002 is a surface-mount ceramic bandpass filter manufactured by RFMi, designed for wireless applications. It operates with a center frequency of 2.48 GHz and provides a bandwidth of 20 MHz at an impedance of 50 Ohms. The component features an insertion loss of 2.5 dB and is housed in a nonstandard package measuring 11.50 mm in length and 7.20 mm in width, with a maximum height of 4.65 mm.

Feature Summary

• Surface mount construction for automated assembly
• Ceramic dielectric technology for stable filtering
• Optimized for 2.4 GHz wireless signal processing

Applications

• Wi-Fi devices operating in the 2.4 GHz band
• Wireless communication modules
• RF front-end circuitry

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and pin configurations before integration. Ensure the surface mount footprint matches the design layout dimensions of 11.50mm x 7.20mm. Confirm that the 2.5dB insertion loss specification aligns with system link budget requirements. Check for any RoHS or REACH compliance documentation required for your region.

Selection Notes

Select this component when a compact ceramic filter is required for 2.48 GHz center frequency applications. The 20 MHz bandwidth suits narrowband wireless protocols. Consider the physical dimensions and surface mount profile for PCB space constraints. Evaluate the insertion loss against system sensitivity needs. This part is suitable for general-purpose Wi-Fi and ISM band filtering tasks.
