BFCN-2450+

Overview

The BFCN-2450+ is a Low Temperature Co-fired Ceramic (LTCC) bandpass filter designed for RF applications. It operates within a passband of 2400 to 2550 MHz with a center frequency of 2.45 GHz. The component features a 50Ω impedance and utilizes wrap-around terminations to minimize parasitic variations. Constructed using multilayer ceramic technology, it offers low insertion loss and high rejection at band-reject edges. The rugged LTCC package ensures high repeatability and performance stability in high humidity and extreme temperature environments.
