The experimental results indicate that on-chip microwave center-tapped transformers can be designed for applications in the frequency range from a few hundred MHz up to more than 50 GHz with an endurable insertion loss. These results are useful for MMIC designs.encircuit designGaAs-TechnologieGaAs technologymicrowave transformerMikrowellen-TransformatorSchaltungsentwurf621667Experimental results of on-chip center-tapped microwave transformersTestergebnisse von On-Chip-Mikrowellen-Transformatoren mit Mittelabgriffconference paper
