Abstract

A novel time domain phase noise analysis and minimization method (TDPNAM) is presented and applied to the design of a 15 GHz microstrip line oscillator. The new method determines the design, e.g., the linear network of oscillators with a minimized phase noise by solving an appropriate optimal control problem numerically. Starting from a design with standard CAD-tools the measured single-sideband phase noise is reduced by 10 dB over the whole offset frequency range to values as low as -100 dBc/Hz at an offset frequency of 100 kHz.<>
