MICROWAVE CONTROL DEVICE Russian patent published in 1997 - IPC

FIELD: radio engineering; switching devices designed to control signal phase and amplitude at high microwave power levels. SUBSTANCE: device has transmission-line section one of whose ends functions as its input and other, as output, and circuit of detector and switching diodes interconnected through their unlike-polarity electrodes, this circuit being connected in parallel with transmission-line section on microwave side; novelty is that connected in parallel with this circuit through microwave choke are control pulse voltage supply and low-frequency filter; control pulse length τ_c is five to ten times lower than that of controlled pulse of microwave signal τ_s, higher boundary frequency τ_h of filter is chosen from condition , and detector diode capacitance is 20-100 times higher than capacitance of switching diode. EFFECT: reduced power requirement of control circuit at high in microwave power and eliminated device operation under the action of microwave signal inherent power. 3 dwg
