sUSING S PARAMETERS

Abstract

This paper focuses on the modeling of ferrite transformers for directional couplers up to 1 GHz. Four port scattering parameters of ferrite transformer were measured. On the basis of measured data, transformer model was built for the lower UHF range. Those passive devices are suitable for a class of small signal amplifiers using a transformer and coupler lossless feedback. Using transformer indefinite S matrix overall dissipation loss was analyzed.
