Composite electromagnetic isolation filters

摘要

The present disclosure is directed to systems and methods for operating, designing, testing and verifying the performance of wireless communication devices. Specifically, the present systems and methods can passively attenuate unwanted electromagnetic interference (EMI) without degrading signal quality of predetermined frequency using a novel versatile module including a RF absorbing material in a composite medium surrounding the conducting signal lines. Utilizing varying permeability media, the present invention offer a robust platform to eliminate unwanted noise while maintaining a desirable control and power interfaces used for testing of wireless communication systems.

主权项

1. An apparatus for mitigating electromagnetic interference, comprising:
a first strip of passive electromagnetically attenuating media; a second strip of passive electromagnetically attenuating media; and one or more electrical conductors extending substantially along a length of the first and second strip; said one or more electrical conductors disposed in between first and second strip; one or more electromagnetic signal interface ports, said electromagnetic signal interface ports in electrical communication with said one or more electrical conductors; and a LC filter element in-line with said electrical conductors so as to sharpen the filter drop-off characteristic of the apparatus.
