Overview
The CDR3005 is a ceramic bandpass filter manufactured by RFMi. It operates with a center frequency of 5.245 GHz and features a bandwidth of 190 MHz. The component is designed for a system impedance of 50 Ohms. Its physical dimensions are 0.333 inches in length and 0.159 inches in width, equivalent to 8.46 mm by 4.04 mm. This device is classified as a DR filter intended for wireless applications.
Feature Summary
- Provides signal filtering within the 5.8 GHz Wi-Fi frequency range
- Utilizes ceramic technology for stable signal processing
- Designed for nonstandard impedance matching at 50 Ohms
Applications
- Wi-Fi 5.8 GHz receiver front-ends
- Wireless networking equipment
- Digital communication systems requiring 5.245 GHz filtering
Procurement Notes
Verify the specific part number suffix, such as -DG, against official RFMi documentation to ensure correct configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributor. Ensure handling precautions for electrostatic sensitive devices are observed during procurement and storage to prevent damage.
Selection Notes
Select this component when a fixed center frequency of 5.245 GHz is required for 5.8 GHz Wi-Fi applications. The 190 MHz bandwidth must align with system channel requirements. Verify that the 50 Ohm impedance matches the surrounding circuit design. Consider the physical footprint of 8.46 mm by 4.04 mm for PCB layout constraints.
Part Context
RFMi, an Akoustis brand, specializes in RF components using SAW, crystal, and ceramic technologies. The CDR3005 belongs to their ceramic filter line, targeting emerging wireless applications. These components support stable signal processing for digital and wireless networks, offering alternatives to other timing and frequency products like oscillators and resonators.
Replacement Considerations
No public substitute part numbers are confirmed in available documentation. Cross-referencing requires identical electrical parameters: 5.245 GHz center frequency, 190 MHz bandwidth, and 50 Ohm impedance. Physical compatibility must be verified if replacing with similar ceramic filters.
