BFCG-1952+

Overview

The BFCG-1952+ is a surface-mount LTCC bandpass filter designed for mmWave frequencies. It features a center frequency of 18.8 GHz with a bandwidth of 4.2 GHz. The device operates within a passband range of 16.8 to 21 GHz and maintains a 50 Ohm impedance. Key electrical specifications include an insertion loss of 2.5 dB. The component is housed in an 0805 (2012 Metric) package, ensuring miniature size and high performance repeatability.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for reliable mmWave operation
• Provides high performance repeatability at millimeter-wave frequencies
• Achieves miniature form factor suitable for space-constrained designs

Applications

• Wireless communication systems operating in the K-band
• Point-to-point microwave radio links
• Satellite communication equipment

Procurement Notes

Verify the specific datasheet revision when ordering, as Mini-Circuits may update documentation over time. Confirm that the + suffix indicates lead-free compliance and RoHS adherence. Ensure the selected evaluation board, such as TB-BFCG-1952C+, matches your PCB material requirements, specifically noting the recommended RO4350 substrate or equivalent with a dielectric constant of 3.5 for optimal testing results.

Selection Notes

Select this component when a compact bandpass filter is required for frequencies around 18.8 GHz. The 0805 package allows for automated surface-mount assembly. Consider the 2.5 dB insertion loss and 4.2 GHz bandwidth against system link budget requirements. This filter is appropriate for applications demanding stable performance in harsh environments due to its ceramic construction.

Part Context

This part belongs to the BFCG series of LTCC bandpass filters from Mini-Circuits. The series is engineered for high-frequency applications where size and performance consistency are critical. Similar models in the lineup offer different center frequencies and bandwidths, allowing designers to tailor RF front-end solutions for various wireless standards without compromising on physical footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Mini-Circuits directly for cross-reference recommendations or verify compatibility with alternative LTCC filters offering similar 18.8 GHz center frequency and 0805 package dimensions.
