Abstract
The present invention addresses the problem to extend the dynamic power range where the amplifier operates linearly for a full input amplitude swing with improved efficiency. According to the present invention, the above presented problem is solved by changing the delivered power to the load by changing the value of the load and still keeping the amplifier in its linear condition. The invention enables the amplifier to maintain high efficiency over a wider power range.
