Abstract
An amplifier includes a main amplifier circuit with an input and output. At least one auxiliary amplifier circuit has an input and output, and is selectively operable to operate in combination with the main amplifier circuit. A signal combining network is coupled with outputs of the main amplifier circuit and auxiliary amplifier circuit and is operable to combine amplifier circuit output signals at an output port. The main and auxiliary amplifier circuits operate in an operational frequency band, and a delay element is coupled to the input of the auxiliary amplifier to introduce a delay to that input that is configured for introducing a delay that is an integer multiple of a wavelength at a frequency within the operational frequency band.
