BFCQ-2802+

Overview

The BFCQ-2802+ is a miniature low-temperature co-fired ceramic (LTCC) bandpass filter designed for high-frequency applications. It features a surface-mountable 1008 (2520 Metric) package with three PC pads, facilitating automated pick-and-place assembly. The device covers the 5G n257 band, providing a passband of 27.5 to 29.5 GHz. It supports up to 1W RF input power and maintains a 50 Ohm impedance. The filter exhibits a passband insertion loss as low as 2dB, ensuring efficient signal transmission in demanding microwave environments.

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update component specifications over time. Confirm that the required passband characteristics align with the 27.5 to 29.5 GHz range defined for the 5G n257 band. Ensure compatibility with standard SMT processes given the 1008 package dimensions. Cross-reference the part number suffix to confirm it denotes the standard commercial grade variant without special modifications.

Selection Notes

Select this component when a compact solution is required for the 5G n257 frequency range. The LTCC construction offers reliability suitable for high-power applications up to 1W. Consider the 1008 footprint constraints during PCB layout design. Evaluate the 2dB insertion loss against system link budget requirements. This filter is appropriate for designs prioritizing size reduction while maintaining performance in the millimeter-wave spectrum.
