Power combiner having a symmetrically arranged cooling body and power combiner arrangement

Abstract

The invention relates to a power combiner (10) comprising a cooling body (40). The power combiner (10) hast at least one first electrical conductor (14) and one second electrical conductor (16). The first electrical conductor (14) and the second electrical conductor (16) are generally mostly arranged equidistant from the cooling body (40). In addition, the first electrical conductor (14) and the second electrical conductor (16) can be arranged alternatingly near or at a distance from the cooling body (40). Alternatively or in addition, the cooling body (40) can be arranged between the first electrical conductor (14) and the second electrical conductor (16). Alternatively or in addition, the first electrical conductor (14) and the second electrical conductor (16) can be divided mostly intoparallel conductor parts (14a, 14b, 16a, 16b), wherein the conductor parts (14a, 14b, 16a, 16b) are distanced from the cooling body (40) in such a way that the first electrical conductor (14) and thesecond electrical conductor (16) are generally mostly at equal distance from the cooling body (40).

Description

technical field [0001] The invention relates to a power combiner for coupling and / or distributing (splitting) high-frequency signals with a frequency greater than 1 MHz into an output power greater than 100 W. Furthermore, the invention relates to a power combiner device having such a power combiner. Background technique [0002] It is known to use power combiners with electrical conductors to combine multiple high-frequency signal sources and / or to distribute (splitting) one high-frequency signal. [0003] From EP 1 699 107 A1 a power combiner is known which has a second electrical conductor spaced apart from a first electrical conductor. The first electrical conductor is capacitively and inductively coupled with the second electrical conductor. According to EP 1 699 107 A1, in order to increase the inductive coupling between the two conductors, both the first electrical conductor and the second electrical conductor can have a plurality of windings.

Problems solved by technology

[0006] However, since the electrical conductor is close to the cooling body, a parasitic capacitance is generated between the cooling body and the electrical conductor: the closer the electrical conductor is to the cooling body, the more efficient the cooling, but the greater the parasitic capacitance

Parasitic capacitances cause the characteristics of the power combiner to change in unfavorable ways and ways
