Abstract:

Research was concerned with the useful applications of synchronization phenomena. In order to take advantage of amplification by synchronization, a laboratory investigation of the locking phenomena of reflex klystrons was undertaken in connection with the secure communications phase of the AGS program. If certain criteria are met,A MICROWAVE OSCILLATOR MAY BE SYNCHRONIZED BY THE INJECTION OF A CONTROLLING SIGNAL INTO THE OSCILLATOR CAVITY. Locking was observed with injection signals 70 db below the oscillator output and 30 db ratios were demonstrated to be easily realizable. Injection locking is a form of amplification that takes advantage of the greater efficiency and availability of oscillator devices in the microwave region of the frequency spectrum. Experimental verification of the theory is shown for 180 degree phase modulation of the locking signal at rates up to 100 kc. Author
