BFHKI-2492+

Overview

The BFHKI-2492+ is a miniature bandpass filter manufactured by Mini-Circuits using low-temperature co-fired ceramic (LTCC) technology. It operates within a frequency range of 22 GHz to 28 GHz, providing a center frequency of 25 GHz with a bandwidth of 6 GHz. The component features a 50 Ohm impedance and utilizes surface-mount device (SMD/SMT) termination styles for integration into printed circuit boards. Designed for high-performance RF applications, it offers ultra-high stopband rejection capabilities. The unit includes an integrated interposer board and shielded construction to ensure signal integrity and minimize interference in dense electronic assemblies.

Feature Summary

• Ultra-high stopband rejection capability utilizing LTCC technology
• Integrated interposer board with shielded construction for enhanced performance
• Miniature form factor suitable for space-constrained SMD/SMT designs

Applications

• Microwave communication systems requiring precise frequency selection
• RF front-end modules in wireless infrastructure
• Test and measurement equipment operating in the K-band spectrum

Procurement Notes

Verify the specific datasheet revision and RoHS/REACH compliance status directly with Mini-Circuits or authorized distributors before procurement. Ensure that the ordering suffix matches the required package configuration. Confirm that the thermal and mechanical specifications align with your assembly processes. Cross-reference the part number against official manufacturer catalogs to avoid counterfeit components. Validate that the intended application environment falls within the specified operational limits.

Selection Notes

Select this component when a compact, high-rejection bandpass filter is required for frequencies between 22 GHz and 28 GHz. The LTCC construction offers stability and reliability for microwave applications. Consider the 50 Ohm impedance match for seamless integration into standard RF transmission lines. Evaluate the physical dimensions against available PCB real estate. Ensure that the shielding requirements are met by the integrated design without additional external casing.

Part Context

The BFHKI series represents Mini-Circuits' line of miniature surface-mount bandpass filters designed for high-frequency applications. These components leverage LTCC technology to achieve superior electrical performance in a small footprint. The series is engineered for use in modern wireless communications and radar systems where size and performance are critical. The BFHKI-2492+ specifically targets the 22-28 GHz range, fitting into the broader portfolio of microwave passive components offered by the manufacturer.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-reference recommendations. Verify that any substitute maintains the same 22-28 GHz passband and 50 Ohm impedance. Ensure the replacement component supports SMD/SMT mounting and offers comparable stopband rejection. Check for identical package dimensions to guarantee mechanical compatibility.
