<p>A pulse controlled phase modulator device converts an unknown phase pulsed input signal to acontinuous wave phase modulated output signal. The pulsed input signal activates a switch, such asa saturable absorber operating near saturation, to pulse modulate a dependent signal that has aknown phase value. A combiner combines the dependent signal with an independent signal toproduce the constant magnitude continuous wave phase modulated output signal. The output signalis a binary phase shift keying signal with the same frequency as the continuous wave input signal. An amplifier or weighted splitter is used to make the dependent signal larger in magnitude than the independent signal and a phase inverter is used to make the dependent and independent signalsopposite in phase.The pulse controlled phase modulator consists of a splitter, an independent stage, a dependent stage, and a combiner. A threshold device is also used on the pulsed dependent signal to inhibit output magnitude variations.</p> |
