The Research And Application Of Microwave High Power Automatic Test System

With the rapid development of science technology and engineering application requirements, people pay more and more attention to the parameter test of RF/Microwave power device under the large-signal condition, the test in semiconductor devices and applications also plays more and more important position. The microwave high power automatic test system based on load/source pull is capable of making user set the known load/source impedance on device under test under actual operation condition. Then the various changes of device parameters and the optimal value can be found.The work in the thesis focuses on the research and the application of the high power automatic test system. It includes the research of 10GHz-40GHz automatic tuner, programming and debugging the software of automatic test system, constructing the practical test system, the frequency/power pull measurement of the VCO, the measurement of, the contour of power and the maximum power of the transistor.
