Abstract
A diode switched microwave phase shifter network consists of a series of alternate path, phase increment stages. The diodes which control direction of current through the alternate paths are all commonly poled so that a single D.C. diode forward biased source applied between the ends of the network operates all the diodes. The alternate paths of each phase increment stage are controlled by the series connection therein of a collector-emitter internal circuit of a low frequency transistor.
