Abstract
The present invention is directed to a network that includes an output matching network coupled to an amplifier. The output matching network is configured to transform the at least one amplifier transistor output impedance to an output matching network impedance. A combiner network is coupled to the output matching network. The combiner network includes a first quarter wavelength transmission line coupled between the in-phase signal path and a combiner node. The combiner network further includes a bandwidth enhancement element coupled to the quadrature signal path at the combiner node and an impedance transformation element coupled between the combiner node and a load. The impedance transformation element is configured to substantially transform a combined output matching network impedance at the combiner node to the load impedance.
