Problems solved by technology

[0005] First, the device loss obtained by using the micro-power test cannot fully characterize its parameters under high-power conditions, and small errors will cause large deviations at high-power conditions; second, when installing microwave transmission feeder components The docking part of each interface will produce an uncertain loss according to the installation situation, so the parameters obtained by the above method will have certain deviations, which will reduce the accuracy of the parameters
