BFCG-162W+

Overview

The BFCG-162W+ is a ceramic bandpass filter manufactured by Mini-Circuits, designed for high-performance RF applications. It operates within a frequency range of 950 MHz to 2200 MHz, with a center frequency of 1.575 GHz. The component features a 50 Ohm impedance and utilizes LTCC technology for miniature size and repeatability. Packaged in a 4-SMD surface-mount module, it offers low insertion loss and high selectivity. This filter is suitable for mmWave frequencies and complies with RoHS and REACH standards.

Feature Summary

• Utilizes proprietary LTCC technology for miniature size and high performance repeatability at mmWave frequencies
• Provides high selectivity and low insertion loss within the specified passband
• Designed as a surface-mount device for automated assembly processes

Applications

• GPS receiver front-end filtering
• Wireless communication systems requiring bandpass filtering
• RF signal processing modules

Procurement Notes

Verify the specific suffix 'W+' ensures compliance with current environmental regulations such as RoHS and REACH. Confirm the package type matches the required PCB footprint. Ensure application conditions do not involve DC voltage at input or output ports, as the filter is not intended for DC blocking. Cross-reference datasheet specifications for insertion loss and return loss requirements against system design needs.

Selection Notes

Select this component when a compact, high-repeatability bandpass filter is needed for frequencies between 950 MHz and 2200 MHz. The 50 Ohm impedance matches standard RF transmission lines. Consider the SMD package for space-constrained designs. Verify that the center frequency of 1.575 GHz aligns with the target signal band. Ensure the operating temperature range meets system requirements.

Part Context

The BFCG series from Mini-Circuits represents a line of ceramic bandpass filters leveraging LTCC technology. These components are engineered for miniaturization and consistent performance in RF circuits. The BFCG-162W+ specifically targets applications around the GPS L1 band, offering a balance of size, cost, and electrical performance for modern wireless devices.

Replacement Considerations

Consult Mini-Circuits documentation for direct replacements within the BFCG series. Verify equivalent frequency ranges and impedance values. Check package compatibility for surface-mount integration. Ensure substitute components meet the same environmental and performance standards.
