Microwave technology has been widely used and developed in various sectors of national defense, communications, science, industry, medical care and national economy. As an important part of microwave technology, microwave circuits and measurement have also developed rapidly. RF / microwave circuits have been widely used, and in communications engineering, radar, satellite systems and other projects, a complete technical system has been formed. The SD3200 microwave experiment training system independently developed and produced by our factory includes SD3200 transceiver experiment system and SD3200MW microwave circuit experiment module box. This product is based on the basic principles of transceivers in microwave communication systems and is equipped with various RF / microwave circuit modules such as low noise amplifiers, power amplifiers, microwave filter amplifiers, mixers, phase-locked oscillators, modulators and demodulators Waiting for more than a dozen circuit modules, and equipped with various microwave passive devices, such as attenuators, filters, power splitters, couplers and other devices. The test needs to be equipped with experimental microwave measurement instruments, such as spectrum analyzer, network analyzer, microwave frequency synthesis signal generator, microwave frequency meter, etc., and various accessories, such as standard load, coaxial attenuator, adapter, Feeders, etc., form a complete set of experimental training systems for microwave communications, microwave circuits and devices. The experimental training system is a practical training system for electronic information, electronic technology applications, microwave technology, electronic measurement and communication engineering in colleges and universities. The system has received timely attention from the education department, especially Qinghai University, Guilin University of Electronic Technology, Beijing University of Chemical Technology, Hebei Network Communication Network Communication College and other colleges and universities, equipped with the experimental training system in time, which improves the students ’experimental ability, greatly Enhance the basic qualities of students in electrical and electronic engineering. After colleges and universities have constructed the laboratory and equipped with the SD3200 microwave circuit experimental training system, through practical teaching, the experimental content has been increased and the experimental level has been improved, which has achieved good results, such as: Guilin University of Electronic Technology, equipped with SD3200 microwave circuit experiment system for the experiment of microwave circuit and measurement, regards the experiment system as an important experiment course of the school. Teacher Guidian agreed that the experiment training system is effective Ability is of great benefit. In order to speed up the marketization process of our products and serve the education industry extensively, our factory has continuously improved the RF / microwave circuit and measurement experimental training system in accordance with the needs of different levels of colleges and universities, and has developed and produced the following new experimental training system: 1. SD3100 high-frequency circuit experiment training system (high-frequency TV transceiver system); 2. SD3100H high-frequency circuit experiment module box (high-frequency circuit and course design training system); 3. SD3300 RF signal distribution experiment system (mobile communication network optimization experiment system) includes: (1) SD3300 GSM radio frequency signal distribution experiment system; (2) SD3300 CDMA radio frequency signal distribution experiment system; (3) SD3300 WCDMA radio frequency signal distribution experiment system; (4) GSM / CDMA dual-band combined system; (5) GSM / WCDMA dual-band combined system. The above-mentioned experimental system fully embodies the current education innovation consciousness, as well as a new teaching system focusing on the cultivation of students 'abilities, strengthening students' research, design abilities and engineering application training. Education users are welcome to come to communicate and negotiate. Shijiazhuang No. 4 Radio Factory is willing to work with teachers and students of the education industry to jointly promote the new development of the electrical and electronic education industry.

Beijing University of Chemical Technology was equipped with the SD3200 microwave circuit experiment system of our factory in 2009. After one year of use, the experiment system has been well received by teachers and students of the school. The use of this system has strengthened the students 'practical ability, improved the students' level of innovation, and enabled students to obtain new theoretical knowledge and improve their practical ability directly through perceptual and practical learning methods. In the course of use, students deepen their understanding of and consolidate the theoretical knowledge of microwave transmitters, receivers, basic principles and wireless transmission characteristics, and use the microwave circuit modules in time for analysis, testing and production, and course design. The circuit module is tested, and the system is used to verify the production of the circuit module, which greatly enhances the practical ability.
