Patent ID: 8120444

Claim:
Circuit for, in use, separating or combining high frequency power, the circuit comprising: a coaxial structure comprising (a) an outer conductor, and (b) a transformation inner conductor disposed within the coaxial outer conductor, the transformation inner conductor extending in a axial direction, the outer conductor having first and second ends, the first end having an end face; a coaxial summation port provided at one of the end-face ends of the outer conductor first end, at the second end of the outer conductor, a head piece comprising at least two single ports, which said ports comprise outer conductor connections, the at least two single ports each being axially penetrated by a respective inner conductor which is connected to the transformation inner conductor, and insulating supports that at least indirectly support the transformation inner conductor relative to the outer conductor, the head piece comprising the at least two single ports being formed in a single piece so as to avoid mechanical connection points, the head piece comprising the at least two single ports structured to form integral outer conductor connections being forged or cast, at least one the single ports extending traversely to the axial direction of the transformation inner conductor, a blind hole being formed in the head piece in axial extension of the single port that extends transversely to the axial direction of the transformation inner conductor, which the blind hole is outwardly closed.
