Product Overview
Mini-Circuits LFCW-113+ is an LTCC low pass filter with a passband from DC to 11 GHz, designed for a variety of applications. It offers a typical passband insertion loss of 1.5 dB and excellent stopband rejection up to 26.5 GHz due to its strategically constructed layout with minimal component interaction. This filter can handle up to 2.5 W of RF input power and operates within a wide temperature range of -55 to +125C. Housed in a compact 0603 ceramic form factor with wraparound terminations, it is ideal for dense PCB layouts and minimizes performance variations caused by parasitics.
