A Wideband Model for a Stacked Millimeter-Wave Transformer-based Power Combiner

Year: 2025

Type: conference-paper

Abstract: This paper presents a wide-band model of a transformer-based power combiner employing simple equations for coil inductances. To verify the model, electromagnetic simulations are performed on two different power combiner dimensions. The model is valid up to over 160 GHz. The power combiner studied is implemented in a 28 nm CMOS process. The equations depend on both the combiner dimensions and the technological parameters, showing good agreement between the model and the electromagnetic simulated data.
