Abstract
A novel coaxial DC block with circumferential capacitive shielding is presented. The coaxial DC block includes an inner DC block electrically couplable to a first inner conductor of a first length of coaxial cable and electrically couplable to a second inner conductor of a second length of coaxial cable. The inner DC block provides a capacitance which capacitively couples the first inner conductor to the second inner conductor and blocks a first frequency range of interest. The inner DC block is electrically sealed and shielded by a capacitive sleeve that is concentrically arranged to form a Faraday cage around the inner DC block. The capacitive sleeve is electrically couplable to a first outer conductor of the first length of coaxial cable and electrically couplable to a second outer conductor of the second length of coaxial cable. The capacitive sleeve forms a circumferential capacitance that electrically circumferentially couples the first outer conductor to the second outer conductor and blocks a second frequency range of interest.
