Abstract
High frequency attenuation cable has a core surrounded by an EMI shielding layer. The core comprises at least one inner conductor, at least one high frequency absorption layer or non-amorphous magnetic metal tape surrounding, but not necessarily adjacent to, the inner conductor, and at least one dielectric layer surrounding, but not necessarily adjacent to, the inner conductor. The constructions according to the invention enable improved attenuation at frequencies in the range of 10-100 MHz.
