Product Description
Product Overview
Mini-Circuits LFCG-575+ is an LTCC low pass filter with a passband from DC to 575 MHz. This model provides 1 dB typical passband insertion loss and excellent stopband rejection (30 dB typical) due to its strategically constructed layout. It handles up to 3.5W RF input power and offers a wide operating temperature range from -55C to 125C. Housed in a tiny 0805 ceramic form factor with wraparound terminations, this filter is ideal for dense PCB layouts and minimizes performance variation due to parasitics.
