Product Overview

Mini-Circuits LFCG-490+ is an LTCC low pass filter designed for applications requiring a passband from DC to 490 MHz. It offers excellent stopband rejection up to 8.5 GHz, low passband insertion loss (1.5 dB typical), and robust power handling up to 3.5W. Its compact 0805 ceramic form factor with wraparound terminations makes it ideal for dense PCB layouts and harsh environmental conditions. The filter is suitable for harmonic rejection, VHF/UHF transmitters/receivers, military radar, test and measurement, telecommunications, and broadband wireless applications.
