BFCN-4800+

Overview

The BFCN-4800+ is a ceramic bandpass filter manufactured by Mini-Circuits, designed for RF applications. It features a center frequency of 4800 MHz with an 800 MHz bandwidth. The component operates at a nominal impedance of 50 Ohms and utilizes a 4-SMD, no lead package style.

Feature Summary

• Provides selective signal filtering within the S-band frequency range
• Utilizes LTCC technology for stable performance in compact form factors
• Designed for surface-mount integration into PCB assemblies

Applications

• S-band upconverter circuits
• RF front-end modules
• Satellite communication systems

Procurement Notes

Verify the specific datasheet version to confirm electrical parameters such as insertion loss and rejection levels. Ensure the 4-SMD package footprint matches the target PCB layout. Confirm that the 50 Ohm impedance aligns with system requirements before finalizing procurement.

Selection Notes

Select this component when a fixed center frequency of 4800 MHz is required. The 800 MHz bandwidth suits applications needing moderate selectivity. The surface-mount package facilitates automated assembly processes for high-volume production environments.

Part Context

This part belongs to Mini-Circuits' BFCN series of LTCC bandpass filters. These components are engineered for reliability in demanding RF environments. The series offers various center frequencies to support diverse communication standards and frequency planning needs.

Replacement Considerations

Check for direct substitutes within the BFCN series with adjusted center frequencies. Evaluate alternative LTCC filters from other manufacturers if pin compatibility and impedance specifications match the original design constraints.
