Abstract

Present paper deals with a new active uniplanar power combiner/divider which presents major interest for MMICs future applications. Its design takes advantages on uniplanar interconnection technology based on coplanar strips and waveguides (CPS and CPW). Moreover, this circuit allows to realise either a 180° out of phase power combiner or a 180° out of phase power divider. Finally, it offers new potentialities compared to the early published basic circuits, featuring superior electrical performances such as an improved gain value (about 9 dB) and a suitability for an integration in more complete functions as balanced mixers.
