Abstract

It is well known that mm-waves have an important role to play in the rapid expansion of mobile and personal communications, mmic technology is an important factor since it can provide a means of mass producing the user terminal rf subsystems. Millimetre-wave integrated circuits do not yet however offer the high packing density and functionality which is now possible for lower frequency applications where lumped elements are used. This problem is influenced most of all by the extreme modelling difficulties encountered at frequencies above 30 GHz. This paper reviews the current state-of-the-art for cad techniques used in mmic design. It describes some limitations of the standard Smarttm library approach and looks at the application of commercial electromagnetic simulators in the design of both microstrip and cpw circuits.

Résumé

Les ondes millimétriques ont un rôle clef dans les communications mobiles. La technologie mmic fournit un moyen de fabriquer à grande échelle des composants pour les terminaux d’usager. Mais les circuits intégrés fonctionnant aux ondes millimétriques ne présentent pas encore la miniaturisation et les fonctions qui sont maintenant possibles à des fréquences inférieures en utilisant des éléments de circuits localisés. Ce probléme est en majeure partie dû aux difficultés de la modélisation aux fréquences supérieures à 30 GHz. L’article donne un aperçu de I’état de I’art des techniques cao utilisées pour la technologie mmic. // décrit ensuite quelques limitations de l’approche classique par bibliothèque Smarttm et étudie I’application de simulateurs électromagnétiques commerciaux à la conception de circuits en technologie microruban ou coplanaire (cpw).
