CDR3009

Overview

The RFMi CDR3009 is a surface-mount bandpass ceramic filter designed for wireless applications. It operates at a center frequency of 5.697 GHz with a bandwidth of 360 MHz. The component features a 50 Ohm impedance and an insertion loss of 2.5 dB. It utilizes a nonstandard package configuration suitable for board mounting.

Feature Summary

• Provides signal conditioning through bandpass filtering capabilities
• Engineered for high-frequency wireless signal processing
• Utilizes ceramic construction for stable performance

Applications

• Wi-Fi 5.8 GHz systems
• Wireless communication modules
• RF signal conditioning circuits

Procurement Notes

Verify the specific package dimensions against design constraints, as the datasheet classifies the housing as nonstandard. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to integration. Ensure the 50 Ohm impedance matches the system requirements for optimal signal transfer.

Selection Notes

Select this component when a fixed center frequency near 5.7 GHz is required for Wi-Fi bands. The 360 MHz bandwidth supports standard channel allocations in this range. Consider the nonstandard footprint during PCB layout planning to ensure adequate clearance and soldering compatibility.

Part Context

This part belongs to the RFMi ceramic filter portfolio, which targets emerging wireless technologies. It complements other timing and frequency products like SAW resonators and oscillators offered by the manufacturer for complete RF front-end solutions.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Verify electrical equivalence carefully if considering alternatives from other manufacturers.
