CDR4003

Overview

The CDR4003 is a ceramic bandpass filter manufactured by RFMi. It operates with a center frequency of 5.67GHz and provides a bandwidth of 380 MHz. The component features a 50 Ohm impedance rating and utilizes a nonstandard package configuration. Its physical dimensions are specified as 0.128 inches in length by 0.100 inches in width, equivalent to 3.25mm x 2.55mm. This device is designed for high-frequency signal filtering applications.

Feature Summary

Utilizes ceramic technology for stable RF performance
Designed specifically for digital wireless communication systems
Provides precise bandpass filtering characteristics

Applications

WiFi 5 network infrastructure
WiFi 6 network infrastructure
Digital wireless communication devices

Procurement Notes

Verify the specific datasheet version before procurement, as specifications may vary between revisions. Confirm that the nonstandard package dimensions align with your PCB layout requirements. Ensure compatibility with WiFi 5 and WiFi 6 standards if used in modern wireless networks. Check RoHS compliance status for regulatory adherence in target markets.

Selection Notes

Select this component when a 5.67GHz center frequency is required for wireless applications. Consider the small footprint of 3.25mm x 2.55mm for space-constrained designs. Evaluate the 380 MHz bandwidth against system spectral requirements. Verify impedance matching at 50 Ohms for optimal signal transmission in RF circuits.
