Product Description
Product Overview
Mini-Circuits LFCG-1575+ is an LTCC low pass filter designed for applications requiring a passband from DC to 1575 MHz. It offers a typical insertion loss of 0.9 dB and excellent stopband rejection of 50 dB typical, achieved through a strategically constructed layout. This filter handles up to 5.5W of RF input power and operates across a wide temperature range of -55C to 125C. Housed in a compact 0805 ceramic form factor with wraparound terminations, it is ideal for dense PCB layouts with minimal performance variation due to parasitics.
