Broadband signal junction with sum signal absorption
A broadband signal junction with sum signal absorption for transmitted signals includes a common hollow conductor with a first predefined cross-section and four laterally-disposed side arm hollow conductors with a predefined cross-section. The cross-sections of the side arm hollow conductors can also be selected to be different. Two first opposing side arm hollow conductors of the four side arm hollow conductors extend along a first axis. Two second opposing side arm hollow conductors of the four side arm hollow conductors extend along a second axis. The first and the second axes are disposed orthogonal to one another and lie in the common plane. The broadband signal junction with sum signal absorption is characterized in that the two first side arm hollow conductors end with a hollow conductor absorber.
