BFHK-1272+

Overview

The BFHK-1272+ is an LTCC bandpass filter with a center frequency of 12.3 GHz and a bandwidth of 900 MHz (11.9 to 12.8 GHz). It features a 50 Ohm impedance, 4.5 dB insertion loss, and operates from -55°C to +125°C in an 1812 surface-mount package.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust signal conditioning
• Provides high stopband rejection typically between 90dB and 100dB
• Designed for surface-mount board integration

Applications

• S-band upconverter assemblies
• Wireless communication systems
• RF signal filtering

Procurement Notes

Verify the specific datasheet version for the BFHK-1272+ to confirm exact performance curves and PCB layout requirements. Ensure compatibility with 1812 footprint dimensions and thermal specifications during integration.

Selection Notes

Select this component for applications requiring precise filtering around 12.3 GHz with moderate bandwidth. The wide operating temperature range supports industrial and harsh environment deployments where stability is critical.

Part Context

Part of the Mini-Circuits BFHK series, which covers frequencies from 4.5 GHz to 23.8 GHz. These filters are engineered for high performance in RF and microwave signal processing tasks.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes within the BFHK series that match the 12.3 GHz center frequency and 1812 package constraints.
