Abstract
A signal multiplexer for N channel signals of different frequency bands that utilizes only N+1 hybrid couplers and presents a constant impedance to the transmitters that supply the N channel signals. The channel signals are coupled by separate ones of N of the N+1 hybrid couplers to N pairs of matched band pass filters. The outputs of the filters are combined in a signal combiner to form a pair of quadrature phase multiplexed channel signals that are converted to a single multiplexed output signal by the remaining hybrid coupler.
