Product Description
Product Overview
Mini-Circuits LFCG-2750+ is an LTCC low pass filter with a passband from DC to 2750 MHz, designed for a variety of applications. It offers typical 1.2 dB passband insertion loss and excellent stopband rejection due to its strategically constructed layout. The filter handles up to 4.5W RF input power and operates within a wide temperature range of -55 to +125C. Housed in a tiny 0805 ceramic form factor with wraparound terminations, it is ideal for dense PCB layouts and minimizes performance variation due to parasitics.
