Patent abstract
A power amplifier based on a voltage-coupling scheme is disclosed. The power amplifier includes two active elements connected to each other via a primary part of a transformer, in which one of the two active elements is connected to a power-supply voltage of the amplifier, the other one is connected to a ground terminal of the amplifier, and an output power appears in a secondary part of the transformer. Therefore, a potential difference between ports of the active elements is decreased, resulting in increased reliability of the power amplifier.
