Power combiner with symmetrically arranged cooling bodies and power combiner arrangement

Abstract

The invention relates to a power combiner (10) with a cooling body (40). The power combiner (10) has at least one first electrical conductor (14) and a second electrical conductor (16). The first electrical conductor ( 14 ) and the second electrical conductor ( 16 ) are generally spaced apart from the heat sink ( 40 ) as equidistantly as possible. To this end, the first electrical conductor (14) and the second electrical conductor (16) are alternately arranged close to or remote from the heat sink (40). Alternatively or additionally, the cooling body (40) can be arranged between the first electrical conductor (14) and the second electrical conductor (16). Alternatively or additionally, the first electrical conductor (14) and the second electrical conductor (16) are divided as far as possible into parallel conductor segments (14a, 14b, 16a, 16b), wherein the conductor segments (14a, 14b, 16a, 16b) are spaced apart from the cooling body (40) in such a way that the first electrical conductor (14) and the second electrical conductor (16) are generally as close as possible to the cooling body (40) equally spaced.

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
