FIELD: radio engineering, communication.SUBSTANCE: switch comprises four waveguide H-junctions lying in pairs in orthogonal planes, with input and output straight arms and half-wave side arms, combined through a communication window into a full waveguide cross-section in the cylindrical wall of a transmission resonator. The transmission resonator accommodates a microwave switch with a gas-discharge tube, mounted at half the height of the transmission resonator on its diameter at an angle of 45° to the direction of the side arms, and with an illumination discharge device at the centre of one of the ends of the gas-discharge tube. The operating frequency of the transmission resonator is selected equal to the frequency at which the side arms of the H-junction have a half-wave electric length. The outer diameter d1 of the gas-discharge tube is approximately equal to ?/6, and its inner diameter d2 is approximately equal to ?/10.EFFECT: high operating power of the switch with fixed triggering stability and high triggering stability with fixed operating power by increasing the number of channels through which accumulated energy is output from a large number of resonators.3 cl, 2 dwg |
