The microwave switch reduces the insertion loss and improves the bearing large power.

Description

technical field [0001] The invention relates to the technical field of high-power microwave devices, in particular to an improved stripline high-power microwave switch and a manufacturing method thereof. Background technique [0002] Microstrip lines are usually used as the transmission carrier for microwave switches, and bare-core chips are often used for diodes. DC blocking capacitors are generally installed on the transmission main line to block the driving current of the drive circuit. Therefore, the power carried by the device is very limited, and the insertion loss is relatively high. At the same time, the assembly process requirements are relatively strict, and the high-power waveguide microwave switch can withstand relatively large power, but when the frequency band is relatively low (below the C-band), the volume and weight are relatively large, and the switching time is generally longer , high welding process requirements, reliability is difficult to guarantee.
