COMPARISON BETWEEN SIMULATIONS AND MEASUREMENTS OF LARGE-SIGNAL AND NONLINEAR NOISE BEHAVIORS OF MMIC ANALOG FREQUENCY-DIVIDER BY 2

For the first time, the large signal and nonlinear noise behaviors of an analog frequency divider has been fully simulated and measured: com parisons between predicted and measured results of this circuit are gi ven. The circuit designed is a monolithic microwave integrated circuit (MMIC) X-band 8.2-4.1-GHz analog frequency divider by two. The large signal analysis relies on the open-loop method extended to synchronous systems. The simulation of noise behavior of such a circuit has been performed by means of the nonlinearities conversion matrices and noise generators correlation matrices analysis.
