WE-CCMF: Design Principles, Layout Guidelines and Measurement Results for High-Speed EMI Filtering

High-speed differential interfaces such as USB, HDMI, DisplayPort and MIPI generate common-mode noise that overlaps with critical wireless bands at 2.4 GHz and 5 GHz.

This webinar introduces the WE-CCMF, a ceramic common mode filter based on multilayer LTCC technology, designed to suppress common-mode EMI while maintaining differential signal integrity at data rates up to 10 Gbps. The presentation covers the underlying design principles, the influence of PCB layout on filter performance, and measurement results including S-parameter characterization and eye diagram analysis across multiple part numbers and layout configurations.

Attendees will leave with the practical knowledge to select the right WE-CCMF variant for their application and to integrate it effectively into their PCB layout - reducing design iterations and helping to achieve EMC compliance with confidence.
