ABSTRACT:
A pulse amplifier has a driver stage and a following splitter/combiner stage for power division onto two output stages connected in parallel as well as a further splitter/combiner stage that combines the output signals of the output stages. The two splitter/combiner stages each comprise a respective further decoupled port each of which is respectively connected to a switch-over device. The further ports are connected to terminating impedances in a first switch position of the switch-over devices and are connected to one another via an additional signal path in a second switch position and the output stages can be respectively terminated with low impedances at their input sides and output sides via switch elements.
