Abstract
Systems and methods for enhanced high frequency power bias tee designs are provided. In one embodiment, a bias tee network comprises: a first port configured to couple across a data line comprising a first electrically conducting line and a second electrically conducting line; a second port configured to couple to a power port of an electrical device; and a distributed impedance interface coupled between the power supply unit and the differential data line, wherein the distributed impedance interface includes a ferrite impedance gradation network having a plurality of ferrite impedance elements series coupled in an order of progressing impedance, wherein a low impedance end of the first ferrite impedance gradation network is coupled to the first port.
