Advances in linear and non-linear modeling for improved microwave design

This paper addresses two areas of improvement to microwave linear and non-linear modeling. The first area concerns best-practice application examples of electromagnetic (EM) analysis combined with accurate broad-band parasitic models for improved board-based designs using surface mount components. The focus is on co-simulation - which combines circuit and EM simulation - of surface mount capacitors in shunt configurations. The second area that is covered in this paper is to study the X-parameter modeling technique used in characterizing nonlinear devices compared to traditional compact modeling technique. The results show that X-parameter models can be helpful for compact model validation and can also provide a good alternative to compact models for specific devices and operating conditions.
