BFHK-1572+

Overview

The BFHK-1572+ is an LTCC band pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates with a center frequency of 15.6 GHz and provides a bandwidth of 3.6 GHz, covering the range from 13900 MHz to 17500 MHz. The component features a rejection level of 60 dB and utilizes a 3-SMD, no-lead surface mount package. Its physical dimensions are 4.50 mm in length, 3.20 mm in width, and a maximum height of 1.62 mm. The device is RoHS compliant and classified under EAR99.

Feature Summary

• Utilizes proprietary LTCC material system for high performance repeatability
• Miniature footprint enables high circuit board layout density
• Surface mountable design suitable for very high frequency applications

Applications

• EMI/RFI suppression
• Power line filtering
• RF signal conditioning

Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape and reel or cut tape options. Confirm that the LTCC construction aligns with your thermal management requirements. Ensure the 50 Ohm impedance matches your system interface. Check for any recent product change notices regarding the LTCC material specifications.

Selection Notes

Select this component when a compact band pass filter is needed for frequencies around 15.6 GHz. The 3.6 GHz bandwidth offers moderate selectivity for wideband applications. Consider the 3-SMD package for automated assembly processes. Evaluate the 60 dB rejection against your specific interference mitigation requirements.
