Abstract
Electrical apparatus for connecting a radio frequency power-supply having two outputs to a load includes two radio frequency transmission-lines, each one connected to a corresponding power-supply output. A transformer arrangement connects the two transmission-lines to the load. Each transmission-line includes a series-connected pair of twelfth-wave transmission-line sections. The series-connection between the twelfth wave transmission-line sections in one transmission line is connected to the series-connection between the twelfth-wave transmission-line sections in the other by a device having an adjustable impedance.
