  • Abstract
    A new model of a three-port transformer, with a ferrite core is presented. The transformer´s operating frequency lies in the VHF and lower UHF range. The presented model is compatible with most common computer programs for network analysis and synthesis. A measurement method is given for model parameter extraction, including a discussion of stray elements and loss mechanisms. Application of the transformer model to a feedback amplifier with two stages, each with a ferrite transformer in its feedback network, proves the validity of the model
