Method for high-power combining

Abstract:

An apparatus for high-power combining includes multiple power-combining building blocks, a passive input network to couple one or more input signals to one or more input ports of the multiple power-combining building blocks, and a passive output network to couple to output ports of the multiple power-combining building blocks and to generate one or more amplified output signals. Each power-combining building block includes M high-power amplifiers (HPAs) coupled in parallel to a respective passive input network and a respective passive output network. A count of the multiple power-combining building blocks is determined based on a desired total number N of the HPAs and a number M of the HPAs in each power-combining building block.
