Abstract:
A signal combiner, comprising:a plurality of inputs receiving respective input signals, each of the inputs having a respective input impedance;first and second transforming devices having respective first and second transforming impedances, one of the transforming devices receiving a transforming device input signal formed from at least one of the input signals, an equivalent impedance being determined as a function of a number of the inputs forming the transforming device input signal;an output, having an output impedance, electrically connected to the one of the transforming devices, an output signal, which is formed as a function of the transforming device input signal, being produced by the output, the one of the transforming devices matching the equivalent impedance to the output impedance within a tolerance; anda first switch electrically connected to at least one of the inputs, the first switch also being electrically and selectively connected to the one of the transforming devices.
