Product Description
Product Overview
Mini-Circuits LFCG-1700+ is an LTCC low pass filter designed for applications requiring a passband from DC to 1700 MHz. It offers excellent stopband rejection (50 dB typical) and robust power handling (5.5W). Its tiny 0805 ceramic form factor makes it ideal for dense PCB layouts with minimal parasitic effects. The filter operates across a wide temperature range of -55C to +125C.
