A radio-frequency assembly is described which can be used in communication satellites, for example. The radio-frequency assembly contains a signal source in the form of a semiconductor amplifier output, an impedance matching filter, and a radio-frequency waveguide. The impedance matching filter is connected to the semiconductor amplifier output on the input side and to the radio-frequency waveguide on the output side. The impedance matching filter has a different impedance value on the input side from that on the output side and is matched to the semiconductor amplifier output on the input side and matched to the radio-frequency waveguide on the output side. Consequently, a separate matching circuit between semiconductor amplifier output and radio-frequency waveguide is no longer necessary.

A connecting unit for radio-frequency components has: a housing; a first interface and a second interface which are arranged on the housing and are designed to be coupled to in each case one radio-frequency component; an internal conductor which runs in the housing and is connected to the first interface and the second interface in order to establish a radio-frequency connection between the first interface and the second interface; a spacer which surrounds the internal conductor and extends at least along a portion of the length of the internal conductor. The housing is manufactured from an electrically conductive and rigid material and the spacer is arranged such that the internal conductor is at a distance from the housing at least in sections.
