Locking Behavior of a Microwave Multiple-Device Ladder Oscillator

This paper presents a detailed discussion on the injection-Iocking property of a microwave ladder oscillator which is essentially an array of diode mount-pairs in a rectangular waveguide cavity. It is shown both analytically and experimentally that the use of a ladder structure is advantageous both in obtaining a large locking figure of merit (i.e., 2Q_ex^-1) and in rapidity of the transient response to the PSK signal injection.
