Mini-Circuits LFCN-123 Low Pass Filter Microwave Component with Low Insertion Loss and High Rejection
Product Overview
The LFCN-123+ Low Pass Filter offers microwave communication system designers the ability to reject unwanted harmonics with defined RF parameters. Its multilayer LTCC construction ensures high repeatability of performance, while small wrap-around terminations minimize parasitic variations. Covering DC-12000 MHz, these filters provide low insertion loss and good rejection.
