We have had quite a few topics here on RFIC EM modelling in the past, so I wanted to share an application note on 60 GHz RFIC balun design that I just finished.
In this document, two on-chip transformer layout styles with 2:1 turn ratio are compared. Target frequency is 60 GHz, nominal impedances are 200 Ohm primary and 50 Ohm secondary. Technology used for this study is IHP SG13S.
Part 1: Design and choice between interleaved and overlay configuration

Part 2: Investigating the effect of dummy metal fill on balun performance
