Product Description
Product Overview
The BFCN-1445+ LTCC Band Pass Filter is a miniature, 12-layer filter designed for high repeatability of performance. It offers a passband of 1420-1470 MHz with low insertion loss (2.0 dB typical) and sharp rejection peaks. Its small size (3.2mm x 1.6mm) allows for high layout density, while wrap-around terminations minimize parasitic variations. This filter is well-suited for applications requiring harmonic rejection in transmitters and receivers.
