Product Overview

Mini-Circuits LFCW-1142+ is a Low Temperature Co-fired Ceramic (LTCC) low pass filter, designed in a very small, 0603 package. The multilayer construction provides high repeatability of performance. Small, wrap-around terminations minimize variations in performance due to parasitics. Covering DC 11.4 GHz, these units offer low insertion loss, good rejection, and excellent power handling capability. The small size allows for high layout density of circuit boards while minimizing the effects of parasitics. Wrap-around terminations provide excellent solderability and easy visual inspection. The LTCC construction results in a rugged package, well-suited for tough environments including high humidity and high temperature extremes.
