Abstract: A broadband directional coupler for measuring a power of a forward or returning high-frequency signal on a coaxial line provides a voltage splitter comprising a first resistor, a second resistor and a third resistor. The first connection of the first resistor is connected to an inner conductor of the coaxial line, the second connection of the first resistor and the first connection of the second resistor are connected to a measuring unit. The first connection of the third resistor is connected to an outer conductor of the coaxial line and to the second connection of the second resistor. The second connection of the third resistor is connected to a ground. The third resistor is annular in shape and arranged concentrically to the inner conductor in a plane orientated orthogonally relative to the inner conductor.

Abstract: A high-frequency signal combiner comprises at least one first bridge coupler for the transformation of two input-end, first high-frequency signals into at least two output-end, first high-frequency signals in each case with identical power, and a second bridge coupler for the transformation of four input-end, second high-frequency signals, in each case with identical power, into an output-end, second high-frequency signal, of which the power corresponds to the summated power of the four input-end, second high-frequency signals. In this context, the four input-end, second high-frequency signals are each supplied from one output-end, first high-frequency signal. In order to add an integer multiple of four high-frequency signals, a cascade of second bridge couplers is realized with a number of cascade stages corresponding to the integer multiple. In every cascade stage, every second bridge coupler of the preceding cascade stage is replaced respectively by four second bridge couplers.

Abstract: The broadband directional coupler is used for measuring the power of a forward and/or a returning high-frequency signal on a line. For this purpose, the broadband directional coupler provides a voltage splitter which is connected to an inner conductor (1) of the line. This voltage splitter provides a first resistor (8) which is connected to an outer conductor of the line. The voltage splitter comprises ohmic resistors, and a first connection of a second resistor (4) is connected to the inner conductor (1) of the line, and a second connection of the second resistor (4) is connected to a first connection of a third resistor (6). A second connection of the third resistor (6) is connected directly or indirectly to a first connection of the first resistor (8) and at the same time to the outer conductor of the line. In this context, a measured voltage is picked up at the second connection of the second resistor (4) or at the first connection of the third resistor (6).

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.

Abstract: An elongated elastic bandage includes a plurality of hook fastener strips on a first side and a plurality of loop fastener strips on a second side. The hook fastener strips are generally aligned with the longer dimension of the elastic bandage while the loop fastener strips extend across the width of the bandage. In use, the hook and loop fastener strips form a criss-cross configuration when the elastic bandage encircles a portion of a users body.
