AWR Connected - AMCAD

Stability Analysis

AWR Connected™ – AMCAD provides ready access between NI AWR Design Environment and AMCAD Engineering stability analysis (STAN) software. Stability can be difficult to achieve in microwave circuits but with the AWR Connected wizard that links STAN into NI AWR Design Environment, the tool can be called upon from within Microwave Office circuit design software to locate and characterize the unwanted oscillations in components such as power amplifiers (PAs). 

Microwave Office And STAN

AMCAD Engineering STAN software is a revolutionary stability analysis technique for microwave circuits that's valid for small-signal and large-signal regimes. Its patented technique, which has been developed by the University of Basque Country and the French Space Agency (CNES) is able to detect and determine the nature of oscillations, such as parametric oscillations in power amplifiers that can be, for example, a function of the input drive signal. Knowledge of the type of oscillation mode facilitates the insertion of stabilization networks and enables the circuit designer to strike a good balance between required oscillation avoidance and circuit performance.

Armed with knowledge as to the type of oscillation mode, AWR Connected for AMCAD STAN software users are then able to insert the appropriate stabilization network and avoid unwanted oscillations. STAN software is user friendly and intuitive to use for analyzing linear and nonlinear stabilities.
