Passive Elements Modeling in Microwave/Millimeter-wave Application

摘要

Passive elements (e.g., transmission line, transformer and balun) are widely used in Microwave/Millimeter-wave (MMW) applications. Compared with time-consuming Electromagnetic simulation, equivalent circuit based compact models for these passive elements are more preferable for IC designers. However, most of existing equivalent-circuit models only cover low-frequency characteristic, which is not suitable for MMW applications. In this work, we presented new compact models for passive elements in MMW applications. Experimental results show that the proposed compact models are accurate enough over the entire frequency range up to 67GHz for both transmission line and transformer when the distributive coupling between the metal tracks and substrate effect are emphasized.
