Mini-Circuits LFCW-5000+ is an LTCC low pass filter with a passband from DC to 5000 MHz, supporting a variety of applications. This model provides 1.6 dB typical passband insertion loss and offers very good stopband rejection due to its strategically constructed layout with minimal interaction between components. It handles up to 2.5W RF input power and provides a wide operating temperature range from -55 to +125C. Housed in a tiny 0603 ceramic form factor with wraparound terminations, the filter is ideal for dense PCB layouts with minimal performance variation due to parasitics. Its ultra-wide stopband extends to 26.5 GHz, making it suitable for high-end applications. The LTCC construction provides repeatable performance in a rugged, ceramic package, well-suited for tough environments. Applications include harmonic rejection, VHF/UHF transmitters/receivers, test and measurements, telecommunications and broadband wireless systems, military applications, and Satcom modems.
