BFCN-7700+

Overview

The BFCN-7700+ is a ceramic bandpass filter designed for the 7.7 GHz frequency range. It features a center frequency of 7.7 GHz with a bandwidth of 400 MHz and operates at a standard impedance of 50 Ohms. The component utilizes Low-Temperature Co-fired Ceramic (LTCC) technology, constructed with five layers to ensure high performance repeatability and miniature size. It employs a wrap-around termination style in a 4-SMD, no-lead package, allowing for high circuit board layout density while minimizing parasitic effects.

Feature Summary

• Constructed using five-layer LTCC technology for high performance repeatability
• Wrap-around termination style minimizes parasitic effects
• Provides good rejection of signals near the pass band edges

Applications

• RF front-end filtering in wireless communication systems
• Signal conditioning in radar applications
• Component integration in satellite communications equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update mechanical dimensions or electrical tolerances over time. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure the 50 Ohm impedance aligns with your system design. Check for any RoHS compliance markings if required by your manufacturing standards. Validate the center frequency specification against your application needs before finalizing procurement.

Selection Notes

Select this component when a compact, high-repeatability bandpass filter is needed for the 7.7 GHz band. The LTCC construction offers advantages in thermal stability and size compared to traditional cavity filters. Consider the 400 MHz bandwidth relative to your signal requirements. The SMD package facilitates automated assembly. Evaluate the insertion loss and rejection characteristics against your system's noise figure and interference constraints.
