Abstract :
A wideband configuration for a transmission injection-locked (IL) dielectric-resonator oscillator (DRO) is presented. An example of a 9.5-GHz ILDRO with a locking time of less than 100 ns for the final frequency to be within +or-1 p.p.m. of the reference frequency is described. The wideband feature that results from the quadratic coupling configuration used is explained. The effect of the injection gain and resonator Q on the locking time is shown and the isolation of the DRO performance from vibration is demonstrated.<>
