Abstract :
It is shown analytically that impedance-transforming planar Marchand baluns can be designed. A GaAs monolithic CPW balun, transforming between a 50 /spl Omega/ source impedance and 160 /spl Omega/ load terminations has been realised to demonstrate the technique. The balun operates from 40 to 90 GHz with excellent performance.
