ABSTRACT:
Disclosed is a hyperfrequency device which includes a triple plate line in which at least two diodes exert their action at the same point on the suspended line. Instead of connecting the two diodes on both sides of the suspended line, they are mounted on the same side, this is possible by providing two subsidiary line sections orthogonal to the main line and in the same hyperfrequency plane. A diode is connected to the end of each subsidiary line at a point distant by .lambda.g/2 from the central point of the main line. The action of the two diodes is thus brought back to this point.
