ABSTRACT:
The invention relates to a diode switch for the optional switch-through of an input-end signal to an output, in which two diodes, poled oppositely to one another, are arranged in the series arm and a third diode is arranged in the shunt arm of a four-pole, and wherein the different switching states are determined by the conductive state of the oppositely poled diodes and of the third diode, with a simultaneous blockage of the particular other diodes. The four-pole is preceded by an impedance transformer having a very low output resistance and is followed by a transformer having a very high input resistance. A first constant current source having a current strength of J.sub.1 /2 is connected after the output of the series arm diode; a second constant current source having a current strength of J.sub.1 is connected to the nodal point of the diode with a polarity which is such that the oppositely poled diodes are each traversed by a current having a strength of J.sub.1 /2. On the disconnection of the second constant current source, a third constant current source is connected to the nodal point with a polarity which is such that the shunt arm diode is traversed by its current. Following the output and series arm diode during the connection of a third constant current source a blocking voltage is connected which is substantially matched to a bias voltage occurring at the output of the input and impedance transformer.
