Coaxial DC block
First Claim
1. A DC block couplable in series between a first coaxial cable and a second coaxial cable, said first coaxial cable comprising a first dielectric concentrically sandwiched between a first inner conductor and a first outer conductor concentric to said first inner conductor, and said second coaxial cable comprising a second dielectric concentrically sandwiched between a second inner conductor and a second outer conductor concentric to said second inner conductor, said DC block comprising:
- an inner DC block electrically couplable between said first inner conductor of said first coaxial cable and said second inner conductor of said second coaxial cable to form a first capacitance which blocks a first frequency range of interest, and electrically couplable between said first outer conductor of said first coaxial cable and said second outer conductor of said second coaxial cable to form a second capacitance; and
a capacitive sleeve concentrically arranged around said inner DC block that electrically seals said inner DC block, said capacitive sleeve electrically circumferentially capacitively coupling said first outer conductor to said second outer conductor to form a third capacitance, said second capacitance and said third capacitance which together block a second frequency range of interest.

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.
