Product Overview

The BFCN-2491+ LTCC Band Pass Filter offers a miniature 3.2mm x 1.6mm footprint with high performance repeatability. It covers a passband from 1950 to 3190 MHz and provides excellent rejection in the upper stopband. Its small size allows for high circuit board density, while wrap-around terminations minimize parasitic variations. The wide stopband, extending to the 3rd harmonic, makes it suitable for systems with wideband interfering signals. The LTCC construction ensures a rugged package for demanding environments.
