Product Description
Product Overview
The BFCN-3700+ LTCC bandpass filter operates within the 3000 to 4600 MHz passband, featuring 1.9 dB typical insertion loss and significant stopband rejection (28 dB lower, 24 dB upper). It handles up to 2.5W RF input power and maintains stable performance across a wide temperature range of -55 to +100C. Its LTCC multi-layer construction ensures excellent repeatability, and the compact 1206 ceramic package with wraparound terminations minimizes parasitic effects and saves PCB space. This filter is ideal for applications such as harmonic rejection in transmitters and receivers.
