ABSTRACT:
An arrangement for producing a broadband junction between a microstrip line and a coplanar transmission line in the following called "twin band line" provides that the microstrip line and the twin band line (ZL) extend at right angles relative to one another. The ground electrode of the microstrip line and the ground electrode of the twin band line lie immediately one on top of the other. The strip-shaped other electrodes of the microstrip line and the narrower strip-shaped electrode of the asymmetrical twin band line which extends at right angles thereto and coplanar to the wider ground electrode of the twin band line are connected to one another in a broadband manner by one or more ribbons or wires of metal. The arrangement is advantageously employable as a fast integrated optical modulator with cutoff frequencies in the GHz range, whereby the spacing between the coplanar electrodes expediently constricts conically in the longitudinal direction thereof. The arrangement is also advantageously employable for connecting a twin band line to the rigid inner conductor of a coaxial cable.
