BFHK-8501+

Overview

The BFHK-8501+ is an LTCC bandpass filter designed for S-band applications. It operates within a frequency range of 7500 MHz to 8800 MHz with a nominal center frequency of 8100 MHz. The component features a 50Ω impedance and utilizes a miniature NM1812C-3 surface-mount package measuring 4.5x3.2mm. This filter provides high stopband rejection, typically between 90dB and 100dB, ensuring effective signal isolation. It is constructed using proprietary LTCC technology to achieve high performance repeatability and compact form factor suitable for dense PCB layouts.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for high performance repeatability
• Provides high stopband rejection for effective EMI/RFI suppression
• Miniature surface-mount design for space-constrained applications

Applications

• S-band upconverter designs
• EMI/RFI suppression circuits
• Power line filtering systems

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the + suffix indicates lead-free compliance and RoHS adherence. Ensure the receiving facility has appropriate ESD protection protocols, as RF components are sensitive to electrostatic discharge during handling and installation.

Selection Notes

Select this component when a narrow bandpass response in the 7.5GHz to 8.8GHz range is required. The 50Ω impedance matches standard RF transmission lines. Consider the NM1812C-3 footprint for PCB layout compatibility. Evaluate thermal management requirements based on maximum RF power ratings found in the official datasheet before integration into high-power systems.

Part Context

This part belongs to the BFHK series of LTCC bandpass filters from Mini-Circuits. The series covers frequencies from 4.5GHz to 23.8GHz. These filters are engineered for microwave applications requiring stable performance and small size. The BFHK-8501+ specifically targets the upper S-band spectrum, offering a balance of insertion loss and selectivity for communication systems.
