Abstract
A dual-band Doherty amplifier and method therefor are provided. The dual-band Doherty amplifier includes a first amplifier gain element, a first transmission line coupled to a first output of the first amplifier gain element, a second amplifier gain element, a second transmission line coupled to a second output of the second amplifier gain element, and a controller configured, when a signal to be amplified is in a first band, to provide a first bias signal to a first bias input of the first amplifier gain element and a second bias signal to a second bias input of the second amplifier gain element and, when the signal is in a second band, to provide the second bias signal to the first bias input of the first amplifier gain element and the first bias signal to the second bias input of the second amplifier gain element.
