Abstract
An amplifier has an input port, an output port, N gain elements in parallel, an input power splitter coupled between the input port of the amplifier and the input ports of the N gain elements, an output resistor chain extending between the output ports of the first through Nth gain elements, and an output power combiner coupled between the output ports of the N gain elements and the output port of the amplifier. The output power combiner presents a corresponding input impedance to each of the N gain elements. At least two of the input impedances presented by the output power combiner to the N gain elements are substantially different from each other.
