BFHK-1072+

Overview

The BFHK-1072+ is an LTCC bandpass filter from Mini-Circuits, designed for RF and microwave signal conditioning. It operates within a passband of 9.2 GHz to 11.3 GHz with a center frequency of 10.25 GHz. The component features a 50 Ohm impedance and utilizes SMD/SMT surface mount technology in a compact NM1812C-3 package measuring 4.95 mm x 3.65 mm x 1.83 mm. It exhibits an insertion loss of 3.2 dB and functions reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Utilizes proprietary Low Temperature Co-fired Ceramic (LTCC) material system for high performance repeatability
• Provides miniature surface-mount form factor suitable for space-constrained printed circuit boards
• Minimizes parasitic effects through small physical dimensions

Applications

• Wireless communication systems
• Cable television infrastructure
• Industrial control equipment
• Medical electronics
• Aviation radar systems

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters such as insertion loss and bandwidth. Ensure compatibility with standard surface-mount assembly processes. Confirm that the operating environment falls within the specified -55°C to +125°C temperature range. Validate impedance matching requirements for the target application circuit.

Selection Notes

Select this component when a compact bandpass filter is required for frequencies between 9.2 GHz and 11.3 GHz. The LTCC construction offers robustness and repeatability compared to other technologies. Consider the NM1812C-3 package size for layout density constraints. Ensure the system can accommodate the specified 3.2 dB insertion loss.

Part Context

This part belongs to the BFHKI series of bandpass filters from Mini-Circuits, which covers frequencies from 4.3 to 17.5 GHz. The series is characterized by tiny 1812 package styles and stopbands extending up to 40 GHz with over 100 dB rejection. These components are designed for high-reliability applications in RF test solutions and automated production environments.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Cross-reference specifications including center frequency, bandwidth, and package dimensions to ensure functional equivalence.
