Abstract: A multi-stage signal combining network includes two or more first stage combiner circuits, two or more filters, and at least one second stage signal combiner circuit. Each of the first stage combiner circuits has two or more input ports coupled to receive a respective two or more signals, and a first combiner output port. Each of the two or more filters includes an input coupled to one first stage combiner output port and a filter output port. The at least one second stage combiner circuit includes two or more input ports, each coupled to one filter output port, and a second stage combiner output port.
