Product Overview

The Mini-Circuits LFCV-45+ is an LTCC-based 7-section Low Pass Filter designed to extend the lower frequency cutoff range to 45 MHz. It offers a compact SMT chip form factor (EIA 1210 size) integrating up to 7 low pass sections. This filter is suitable for applications requiring high power handling (up to 7W CW) and high rejection (typically 50 dB at 180 MHz), providing a versatile anti-aliasing solution for high data rate receivers. It enables system designers to save power and reduce complexity compared to active or lumped element filtering solutions for lower frequencies.
