Abstract
A distributed weighting network that employs a summing line including distributed summing blocks disposed thereon. Each summing block includes a plurality of resistors that define a resistor divider network. Each summing block includes at least three ports having an input port, an output port and at least one signal port. A signal applied to each signal port of the summing blocks is modified in amplitude by the resistor divider network and summed with the signal propagating along the summing line being input to the input port and output from the output port of each summing block to provide a combined signal. The distributed weighting network can be part of a digital-to-analog converter or a QAM modulator.
