ABSTRACT:
An microwave device of the diode-operated amplitude modulator or switch type is disclosed. The ring is formed by a source of symmetrical currents which powers the diodes connected to a load. When the diodes are off, they show a capacitance which gives a reactive current. To improve isolation or attenuation, the current in the load must be zero. This is obtained by mounting, on diagonals of the ring, two capacitors which give two currents that are equal and opposite to the two reactive currents.
