Degradation of power combining efficiency due to variability among signal sources

The power combining efficiency of a symmetric n-way power combiner depends on the degree of imbalance among its input signals. The worst-case efficiency is established for a combiner when its input signal amplitudes and phases are uncertain, but constrained to given ranges. This result is used to deduce the permissible tolerance in the uniformity of components used in power combiner construction, given the maximum acceptable efficiency degradation.<
