Phase or frequency modulators which utilize phase generators rather than phase shifters to produce low frequency input voltages to single side band modulators. Two phase generators are used to supply the two low frequency input ports of a single side band modulator of the 90 DEG phase shift/side band cancellation type, with the voltage dividers of one phase generator being adjusted so that its output is displaced 90 DEG in phase from the output of the other phase generator.
