BFHK-1742+

Overview

The BFHK-1742+ is an LTCC bandpass filter from Mini-Circuits, operating within a frequency range of 16 GHz to 19 GHz. It features a center frequency of 17.5 GHz and a bandwidth of 3 GHz. The component has a 50 Ohm impedance and utilizes SMD/SMT termination in an 1812 package. It handles up to 1 W RF input power and operates between -55°C and +125°C.

Feature Summary

• Utilizes proprietary LTCC material system for miniature size and highly repeatable performance
• Designed for high stopband rejection capabilities typical of the BFHK series
• Supports wide operating temperature ranges suitable for demanding environments

Applications

• Microwave communication systems
• RF front-end filtering
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and ECAD models when integrating into designs. Confirm that the 1812 footprint matches your PCB layout requirements. Ensure thermal management strategies account for the specified power handling limits during operation.

Selection Notes

Select this component when a narrow 3 GHz bandwidth centered at 17.5 GHz is required. The LTCC construction offers stability across the specified temperature range. Consider the 1812 package size constraints relative to available board space.

Part Context

This part belongs to the BFHK series of bandpass filters, which cover frequencies from 4.5 GHz to 23.8 GHz. Mini-Circuits manufactures these components using LTCC technology to ensure consistent electrical characteristics and physical durability in microwave applications.
