Mini-Circuits LFCW-8400+ is an LTCC low pass filter designed for applications requiring a passband from DC to 8.4 GHz. It offers a typical insertion loss of 1.2 dB and excellent stopband rejection up to 26.5 GHz due to its strategically constructed layout. This filter handles up to 2.5W of RF input power and operates within a wide temperature range of -55 to +125C. Its compact 0603 ceramic form factor with wraparound terminations makes it ideal for dense PCB layouts with minimal parasitic effects. The ultra-wide stopband, LTCC construction for repeatable performance in harsh environments, and good power handling are key advantages.
