The purpose of this seminar is to document the modern predictive RF design process. Hopefully, this will give new RF design engineers good preparation for their first circuit designs. We will focus on design methodology, not on specific mouse or button pushing to operate the tools. In other words, this seminar will not be a step by step description of how to use electronic-design automation software (like circuit and system simulators) or how to operate a network analyzer. We will talk in general terms about which tools to use and when and how to use them. We will also provide some practical design tips based on our case study of a PCS-band transceiver.
