Overview
The BFHKI-7851+ is a miniature low temperature co-fired ceramic (LTCC) ultra-high stopband rejection band pass filter from Mini-Circuits. It operates within a frequency range of 6.7 to 8.6 GHz with a center frequency of 7.7 GHz and a bandwidth of 1.9 GHz. The component features a 50 Ohm impedance, an insertion loss of 3.4 dB, and utilizes SMD/SMT termination styles. Designed for board mounting, it incorporates an integrated interposer board and shielded construction to ensure signal integrity in high-frequency applications.
Feature Summary
- Ultra-high stopband rejection capabilities provided by LTCC technology
- Shielded construction with integrated interposer board for enhanced performance
- Miniature surface-mount design suitable for space-constrained PCBs
Applications
- Wireless communication systems requiring specific bandpass filtering
- RF front-end modules in microwave equipment
- Test and measurement instrumentation operating in the 6.7-8.6 GHz range
Procurement Notes
Verify the exact part number suffix (+) indicates RoHS and REACH compliance when sourcing. Confirm the package type matches the required SMD/SMT footprint for your assembly process. Ensure the operating environment aligns with the specified frequency range and impedance requirements to maintain optimal filter performance.
Selection Notes
Select this component when ultra-high stopband rejection is critical for system noise reduction. The LTCC construction offers stability compared to other filter types. Consider the 3.4 dB insertion loss impact on overall link budget. The shielded design minimizes external interference, making it suitable for dense RF environments where isolation is paramount.
Part Context
This component belongs to the BFHKI series of surface-mount bandpass filters manufactured by Mini-Circuits. The series is characterized by its use of low temperature co-fired ceramic technology and integrated interposer boards. These filters are designed for applications demanding high performance in a compact form factor, covering various frequency bands within the microwave spectrum.
Replacement Considerations
Check Mini-Circuits documentation for direct cross-references or alternative models within the BFHKI series that match the 6.7-8.6 GHz specification. Verify pin compatibility and electrical parameters before substituting any other manufacturer's bandpass filter.
