Studing On The Key Problem Of The RF Microwave Teaching Experimental System

Microwave technology is a theory and practice of closely integrating curriculum,With the university of communications professional attention to microwave experiments, the importance and necessity of microwave experiments is becoming evident. According to the experimental microwave status and the existing experimental conditions, we developed the experimental microwave equipment. Papers on experimental system design, and the overall function of the circuit components are described in detail. The experimental apparatus is characterized by low cost, simple structure. From the most basic microwave modules to achieve the purpose of microwave experiment, the experimental microwave equipment to make the abstract, complex features become easy to achieve.This experimental system is designed with experimental virtual machines, zero intermediate frequency modulation technology and modular circuit. Experimental results show the feasibility and scalability of the experimental system .Using HFSS software designed a dipole antenna, helical antenna and the patch antenna,through experiment proved the reliability of its transmission. The data transmission rate of 19,200 bits can be achieved. Finally, the entire experiment board EMC design for the optimization. Take the electromagnetic protection and the filter processing, simulation and experiment results significantly. The overall performance has been greatly improved.The experimental system using Separation microwave components to achieve the basic characteristics.System is of small size, low cost features. The experimental system has broad prospects, because it is highly scalable.
