POWER AMPLIFIER SYSTEM

摘要

A multiple input multiple output power amplifier system includes multiple main amplifiers (PA 1-A, PA 1-B, PA 1-C) for amplifying corresponding independent input signals (A, B, C). Means (22-C) are provided for forming a composite signal from the independent input signals. This composite signal is amplified by a peaking amplifier (PA2-C) and forwarded to an output network for combining main amplifier output signals with amplified composite signals into multiple power amplifier system output signals.
