Abstract :
A low-noise 1.49 GHz oscillator which uses a novel inline transmission line resonator as the positive feedback element is described. A theory which shows how minimum sideband noise can be obtained from such an oscillator is presented, and the degradation of noise performance with circuit parameters is described. Close agreement between the theoretical and experimental results indicates that it is possible to use a simple linear theory in the accurate design of microwave oscillators with minimum sideband noise performance.
