  • Phase modulator for phase shift key communications systems
    Patent number: 3946337
    Abstract: A carrier wave is directed through a voltage controlled phase shifter to a load. A sample of the signal at the output of the voltage controlled phase shifter is selectably applied, in accordance with modulation information, through one of a plurality of transmission line phase shifters to a phase detector which also receives a sample of the carrier wave. The resulting phase detector output signal is applied through a low pass filter to control the voltage controlled phase shifter.
