Abstract
The present invention provides a novel structure that can be used to make a common mode filter. Only the common mode will be attenuated and the differential mode will not be attenuated. This structure can be implemented in a number of ways, a specific embodiment using strip-line and slot-line junctions is very compact and well-suited to use with multilayer PCBs, and does not require any extra components. It can be designed to attenuate certain discrete frequencies, by designing the poles of the transfer function to be at these frequencies.
