- Strip line 9 and 11 each have a voltage drop of 0.3 - U or 0.3 - U E2 between the actual first and second strip line 9 and 11 and the associated ground line 10 and 12 respectively.
- the input impedance of the high-frequency signal combiner is at the two input ports 1 and 2 due to the series connection of first coaxial line 4 and first stripline 9 and second coaxial line 6 and second stripline 11 at the preferred values for the characteristic impedance of the first and second coaxial and stripline in Embodiment 50 ⁇ each.

- the power P A at the output port 8 results from equations (1) and (2) according to equation (3) from the addition of the powers P and P E2 at the first and second input ports 1 and 2.
- the voltage drop between the inner and outer conductors of the second coaxial line 6 input and output side of the second coaxial line 6 is 0V. Consequently, the voltage drop from the second stripline 11 to the associated ground line 12 is input and
- the output current I A at the output port 8 of the high-frequency signal combiner corresponds according to equation (5) the only current flowing /, through the inner conductor of the first coaxial line 4:
- Coaxial line 6 in the amount of OV to an output-side potential of the outer conductor of the second coaxial line 6 to ground also in the amount of 0.5 -U E. Since that
- Input-side potential of the outer conductor of the second coaxial line 6 due to the non-driven second input port 2 is at ground potential, is a

- Coaxial line 1 and 2 are undesirable, they must be compensated or at least damped. Since these are high-frequency signals, they are already damped to a certain extent by the inductance pads of the first and second coaxial lines 4 and 6 alone.
- Inductance of the first and second coaxial line and thus their damping characteristic is increased by enclosing the first and second coaxial line 4 and 6 with an annular core of a magnetizable material.
- An additional increase in the inductance of the first and second coaxial lines 4 and 6 can be achieved by an advantageous arrangement of the first and second
- Coaxial line 4 and 6 are achieved, as shown below with reference to Figures 4A and 4B.
- Inductances of the first and second coaxial lines 4 and 6 would thus form a series connection between the first and second input ports 1 and 2. If the first and second coaxial lines 4 and 6 were to be in the identical orientation through the recess or bore 20 of the toroidal core 7 - i. Input side end of the first and second coaxial line 4 and 6 on one side of the bore 20 and the output side end of the first and second coaxial line 4 and 6 on the other side of the bore 20 -, we obtain the in Fig. 4A

- Z, Z, + Z-, + 2 «4Z (7)
- Total inductance L for the coupler arrangement of first and second coaxial line 4 and 6 is determined by the
- a toroidal core 7 which, according to FIG. 3, is made of an axially wound band which consists of a first layer 16 of magnetizable iron and of a second layer 17 of a
- insulating layer for example of an oxide or nitride, preferably, consists of an insulating magnesium oxide.
- Toroidal core reduces the eddy current cutoff frequency f
