Abstract:
A reconfigurable Doherty power amplifier includes a packaged power splitter device, main and peaking amplifiers, and a combiner circuit. The power splitter device includes a power divider, input terminals coupled to first and second ports of the power divider, and output terminals coupled to third and fourth ports of the power divider. One of the input terminals is coupled to an RF signal input terminal, and the other input terminal is terminated. The power divider receives an input RF signal, and produces main and peaking RF signals at the third and fourth ports of the power divider, respectively. The main and peaking amplifiers amplify the main and peaking RF signals, respectively. The combiner circuit includes a summing node and a phase delay element between outputs of the main and peaking amplifiers. An RF signal output terminal is coupled to the summing node.
