Feature Summary

• Dielectric ceramic construction for stable RF performance
• Surface-mount design for automated assembly integration
• Band-pass filtering characteristic centered at 6.525 GHz

Applications

• RF signal processing circuits requiring specific band selection
• Wireless communication systems operating near 6.5 GHz
• Microwave receiver front-end stages

Procurement Notes

Verify the exact part number against official ECS Inc. documentation to ensure compatibility with your circuit design. Confirm that the surface-mount package dimensions align with your PCB footprint requirements. Check for any specific handling instructions regarding mechanical stress during soldering, as the component is not hermetically sealed. Ensure supply chain sources provide genuine components to maintain specified electrical characteristics.

Selection Notes

Select this component when a fixed center frequency of 6.525 GHz is required with a 1.2 GHz bandwidth. Consider the 3.5 dB insertion loss specification relative to system sensitivity needs. The 50 Ohm impedance must match the surrounding transmission line architecture. Evaluate the surface-mount form factor against available board space constraints compared to through-hole alternatives.

Part Context

This component belongs to the family of dielectric ceramic filters produced by ECS Inc. These devices utilize ceramic resonator technology to achieve sharp cutoff characteristics and high stability. The ECS-DCF-105 specifically targets microwave frequency ranges, distinguishing it from lower-frequency LC or SAW filters. Its construction allows for miniaturization in high-density electronic assemblies.

Replacement Considerations

No public confirmed substitute part numbers are identified in the provided documentation. Cross-referencing requires matching the 6.525 GHz center frequency, 1.2 GHz bandwidth, 50 Ohm impedance, and 3-SMD package dimensions. Verify electrical equivalence with alternative manufacturers before implementation.
