Microwave High-power Testing System Components Developed

As the development of science and technology, microwave signal is used more widely than before, the most important parameter of microwave signal is power. The measurement and control of microwave signal has become the most important part of microwave technology. So it is very important to construct a microwave power testing system.The paper is mainly based on the research of the microwave high-power testing system, and the testing method has been established. Different parts of the microwave testing system have been designed respectively to construct the whole project. A lot of experiments have been carried out to prove the system.The testing system can be divided into the following discussible problems.1.The Modern technology to test microwave are reviewed in this paper. Based on the practical consideration, the method of diode detector has been used to measure the power. After detailed analysis of the fundamental theory about detector and simulated in ADS software, a new detector has successfully been designed2.A double ridge attenuator has been designed and executed according to the analysis of Wave-guide attenuator.3.Impedance match theory is analyzed, and the method of quarter wave impedance match theory is used to design the ridged wave-guide-micro-strip transformer and ridged wave-guide-coaxial transformer.4.A signal conditioning circuit has been designed to magnify the signals that come from the detector.According to our investigation, the correctness of the theory has been proved, and the testing system which is realizable and practicable has been successfully constructed.
