Abstract
An amplifier (1) is provided, in particular, wideband amplifier with an input (4) and an output (5) comprising a first amplifier stage (2) and a second amplifier stage (3), wherein the first amplifier stage (2) has an active power splitter with at least one injection point, wherein this injection point corresponds to the input (4) of the amplifier, and at least two discharge points (9a, 9b), wherein this active power splitter is formed according to a traveling wave amplifier principle and the second amplifier stage (3) has at least two injection points (11a, 11b) and at least one discharge point, wherein this discharge point corresponds to the output (5) of the amplifier and is formed as a power coupler. It is essential that the second amplifier stage (3) is formed as a power coupler, wherein this power coupler is formed according to the principle of a reactively matched amplifier.
