Patent ID: 8912864

Claim:
A high-frequency signal combiner with a first input terminal for the connection of a first high-frequency signal, a second input terminal for the connection of a second high-frequency signal, an output terminal for the output of a third high-frequency signal combined from the first and the second high-frequency signal, a first coaxial line between the first input terminal and the output terminal, a second coaxial line between the second input terminal and the output terminal and an annular core, through a recess of which the first and second coaxial line are guided, wherein a first microstripline is additionally formed between the input terminal and the output terminal, and a second microstripline is formed between the second input terminal and the output terminal, wherein a surge impedance of the first and second coaxial line is different from a surge impedance of the first and second microstripline, and wherein a physical length of the first and second coaxial line is different from a physical length of the first and second microstripline.
