Abstract
A metallic support supports a number of semi-conductor devices surrounded by an annular dielectric substrate which in turn supports a circuit including at least two microstrip lines and a metallic circular output element. The small thickness and high dielectric constant of the substrate are selected to permit a reduction in width and in length of the microstrip lines which are folded-back in a curvelinear fashion and placed on the substrate along circular arcs which are concentric with the output element.
