Abstract
A multiple input multiple output power amplifier system includes multiple main amplifiers for amplifying corresponding independent input signals. A common control unit forms a composite signal from the independent input signals. The composite signal is amplified by a peaking amplifier and forwarded to an output network where main amplifier output signals are combined with amplified composite signals into multiple power amplifier output signals.
