MICROWAVE SIGNAL DIODE SWITCH Russian patent published in 2021 - IPC H01P1/15 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to switches and limiters of microwave signal power. The diode switch of the microwave signal is made on the basis of a T-connection with two diodes in each arm. The diodes are connected through a quarter-wave line segment, with the first diodes installed at a distance of L/4 from the junction point. Each arm is additionally shunted with a detector diode installed in anti-parallel at a distance of L/4 from the second diode, while a pass capacitor is installed in the transmission line of each arm between the branch point and the first diode.

EFFECT: invention expands the functionality of the device by using the switch as a protective device.
