CDR1000

Overview

The CDR1000 is a ceramic band-pass filter manufactured by RFMi. It operates with a center frequency of 1.945 GHz and features a bandwidth of 410 MHz. The component is designed for 50 Ohm impedance applications. It is housed in a nonstandard surface-mount package.

Feature Summary

• Provides selective frequency filtering within the specified bandwidth
• Designed for high selectivity and low insertion loss
• Hermetic surface-mount construction

Applications

• Wireless communication systems
• Transmitter signal conditioning
• Sub-6G frequency bands

Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration, as the package is classified as nonstandard. Confirm that the 1.945 GHz center frequency aligns with your system requirements. Ensure soldering conditions adhere to the recommended iron temperature of 270±10 °C with preheating at 120 °C to prevent damage.

Selection Notes

Select this component when a fixed center frequency of 1.945 GHz and a 410 MHz bandwidth are required for 50 Ohm systems. Consider the hermetic SMD package for environmental protection. Evaluate the nonstandard footprint against available PCB space. This filter is suitable for applications demanding precise frequency selection without tunability.

Part Context

RFMi, an Akoustis brand, specializes in RF components using SAW, Xtal, and Ceramic technologies. The CDR1000 belongs to their ceramic filter portfolio, which targets digital and wireless infrastructure. These devices serve as critical frequency control elements in transmitters and receivers, offering robust performance in demanding RF environments.

Replacement Considerations

No public confirmed substitute part numbers are available for the CDR1000. Verify compatibility carefully if considering alternatives from other manufacturers, as center frequency and bandwidth specifications must match exactly.
