ABSTRACT:
A phase shifter/modulator which provides linear phase control of a microwave continuous wave carrier signal. Linear phase shift range in excess of 360 degrees is provided as a result of linear variation in control voltage. A reference signal, at a subharmonic of the output carrier signal frequency, is injected into a highly linear fractional range reflection type phase shifter. This fractional phase modulated signal is input to a field effect transistor (FET) based frequency/phase multiplier. The frequency/phase multiplier translates the subharmonic reference signal to the desired output carrier frequency with the full 360 degree phase shift range imposed on the output carrier signal.
