Abstract
A high-frequency signal combiner includes 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 the third high-frequency signal combined from the first and the second high-frequency signal. A first coaxial line extends between the first input terminal and the output terminal. A second coaxial line extends between the second input terminal and the output terminal. Furthermore, an annular core is provided, through the recess of which the first and second coaxial line are guided each in a different direction. The annular core is manufactured from an axially wound strip which includes a first layer made of a magnetizable material and a second layer made of an insulating material.
Claims8
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.
