Abstract
A balanced converter for the microwave range which allows simple construction of modulators and similar electrical assemblies which have particularly good properties as far as noise level and decoupling are concerned. A first embodiment is constructed in microstrip line technology and provides a transition from a line which is asymmetrical to ground and a microstrip and coplanar line to a line which is symmetrical to ground and in which the embodiment is formed from metal strips arranged on a dielectric plate. A second embodiment of the balanced converter is constructed in triplate technology.
