    • An HF plasma process excitation configuration includes an HF generator that is connected to a plasma load through a directional coupler. The directional coupler includes a transmission line, a first coupling line for detecting reflected power from the plasma load, and a second coupling line for detecting forward power from the HF generator, is the first coupling line is spaced apart from the transmission line and is terminated at least at one end with a termination resistance. The second coupling line is spaced apart from the transmission line and is terminated at least at one end with a termination resistance. Each coupling line has a predetermined and adjusted characteristic impedance, and the termination resistances each have a resistance value that corresponds within a tolerance to the characteristic impedance of the associated coupling line with a tolerance.

    • According to an embodiment of the present invention, a high power RF electric signal transmission system such as a TV broadcast system operating in the range of 100 kW at a UHF band includes one or more high power klystrons whose outputs are combined and fed to the first port of a high power Y-junction three port ferrite circulator, the second port of the circulator feeds the broadcast system radiating antenna system, the third port of the circulator feeds a non-reflecting RF load and means are provided for tuning the circulator to compensate for changes in the temperature of the circulator ferrite material, so that the klystron(s) are isolated from reflections from the antenna system. According to another embodiment, means are provided for selectively coupling the second port of the circulator to the radiating antenna system or to a station load whereby the RF power from the klystrons may be switched from the antenna system to the station load without reflected RF from such switching action flowing to the klystron(s).The invention has particular application to a high power HDTV broadcast system due to the particular requirements of HDTV broadcasting, as more fully described herein.

    • A matching network is to be provided which can quickly and easily be tuned to a desired impedance. The matching network has a first and a second line which are interconnected at one end, while their other ends are coupled to a microwave line, and a third line which branches off from the interconnection of the other two lines. The first and/or second line and the third line are loaded with ferrite. The ferrite of the first and/or second line and that of the third line are exposed to separate magnetic fields which can be varied independently of each other.

    • A waveguide junction circulator for a high power application at a high operating frequency. The circulator includes a plurality of connecting waveguides, each of which has a standard height dimension corresponding to the operating frequency; a resonance cavity; a plurality of spaced and cooled, superposed metal plates covered with ferrite discs disposed in the cavity; a magnet disposed outside the cavity for generating a magnetic field oriented perpendicular to the ferrite discs and penetrating the cavity; and a plurality of junction arms each having one end communicating with the cavity and another end forming a connection with a respective one of the plurality of connecting waveguides. The circulator has a height dimension in its region penetrated by the magnetic field that is reduced by at least 20% compared to the standard height dimension of the connecting waveguides. Each connection presents a transition from the connecting waveguide to the junction arm that has a sudden change in cross section from the reduced height of the circulator to the standard height of the connecting waveguide. Reactance elements are provided in the junction arms to form multi-section filters.
