Product Overview
The BFCN-8350+ LTCC Band Pass Filter is a miniature, 5-layer filter designed for high repeatability of performance. It covers 8350 MHz 100 MHz, offering low insertion loss and good rejection at band reject edges. Wrap-around terminations minimize parasitic variations, allowing for high layout density and improved system performance. The LTCC construction provides a rugged package suitable for demanding environments.
