MICROWAVE SWITCH Russian patent published in 2011 - IPC H01P1/15 

FIELD: physics, radio.

SUBSTANCE: invention relates to microwave engineering, particularly to microwave power switches and can be used for microwave channel switching between reception (transmission) channels in microwave receivers (transmitters). The technical result is achieved by that the microwave switch is made from n=3…n transmission line sections which are connected by one end to a common point, from which at least n-1 sections are microwave shunted by k=1…k semiconductor switches. For each section, each first switch from the common connection point is connected at a distance equal to a quarter of the wavelength from the common connection point. Each semiconductor switch is connected to the shunted section by an additional transmission line section whose length is close to a quarter wavelengths.

EFFECT: increase in allowable input power by tens of times compared to devices for the same purpose.
