A CAD system for microwave circuits

We are going to present a Computer Aided Design System for Microwave and high frequency circuits (MICAD). This system deal with the circuit analysis, design and optimisation of amplifiers, oscillators and filters in those frequencies. The designed circuits with MICAD matches very well with their requested performance parameters such as bandwidth, stability, amplification, noise figure. This is verified by many experiments. The system offer to the user the opportunity to use lumped element and/or microstrip components. In the last case, there are taken in account the circuits discontinuity, that permits to use WAD up to tens of GHz. A user friendly graphical interface is offered. MICAD is used to design microwave and high frequency circuits used in several applications. On p the other hand MICAD is a effective tool in the microwave teaching activity in ours laboratories. The MICAD System includes the followings main software modules described in more details in this abstract.
