Nowadays powerful CAD tools allow accurate simulation of the performances of microwave and RF circuits. But the prediction of instabilities giving rise to frequency divisions or spurious oscillations is still a challenge, especially for MMIC designs whose adjustment after fabrication is impossible.
STAN tool offers a revolutionary stability analysis technique of microwave circuits, valid for small-signal and large-signal regimes. This technique is able to detect and determine the nature of oscillations, such as parametric oscillations in power amplifier that can be for example function of the input drive signal. Knowledge of the type of oscillation mode facilitates the insertion of stabilization networks, with a better balance between the required oscillation avoidance and maintaining the original circuit performances.
Compatible with commercial CAD tools for microwave circuit design, STAN tool user-friendly and efficient interface give users a great ability to analyse linear and non-linear stability of their design in an intuitive manner.
