Abstract: In some embodiments, a power divider/combiner assembly includes a divider network, a plurality of amplifiers, and a combiner network. The divider network divides a received divider-network input signal into N divider-network output signals. The divider network includes at least one divider and at least one divider phase-shift circuit. The plurality of amplifiers include N amplifiers for amplifying the divider-network signals. The combiner network is for combining the N amplified signals into a combiner-network output signal. The combiner network includes at least one combiner and at least one combiner phase-shift circuit. Each phase-shift circuit is configured to produce a respective non-zero phase shift between divider output signals or between combiner input signals.
