Abstract
An amplifier arrangement for amplifying an input signal to an output signal for delivering to a load is disclosed. The amplifier arrangement comprises a power splitter configured to receive the input signal and produce split input signals. The amplifier arrangement further comprises a first amplifier branch comprising multiple main amplifier circuits. Output signals of the multiple main amplifier circuits are combined to generate a first output signal. The amplifier arrangement further comprises a second amplifier branch comprising at least one auxiliary amplifier circuit. The at least one auxiliary amplifier circuit is configured to receive a split input signal from the power splitter and produce a second output signal. The amplifier arrangement further comprises a power combiner configured to receive the first and second output signals and produce the output signal for delivering to the load.
