ABSTRACT:
Continuously variable phase shift is obtained by means of two variable phase shifters (20,21) located in two separate, switchable parallel wavepaths (18, 19). The first phase shifter (20) is variable over, at least, the range between zero and 180 degrees. The second phase shifter (21) is variable over, at least, the range between 180 degrees and 360 degrees. Switching means (22, 23) are provided for switching the signal to one or the other phase shifter. A control circuit (16) simultaneously causing the phase shift through the two phase shifters to vary in the opposite sense. When maximum phase shift is reached, the control circuit switches the signal from one phase shifter to the other, thereby providing continuously variable phase shift through the network.
