RF teaching practice system during the RF signal generation and transformation, mixing, filtering, amplification, emission, transmission, reception, demodulation process, so that students can learn more about 1 GHz frequency within RF system of basic structure, working principle, simulation analysis, testing instrument and measuring skill knowledge, mastery of time domain and frequency domain, the transmission line, wave propagation and antenna, RF module and radio frequency communication and other basic concepts, and learn to use important RF test instrument. RF teaching practice system mainly for the colleges and universities to communication engineering, electronic engineering, microwave electronic circuit, microwave technology, and other professional experiment teaching and curriculum design, graduation design, students' secondary development and design.

All, video system in a complete set of system plays a very important role. This system also includes RF wireless communication system, need to use an oscilloscope can see is the reduction of emission signal. RF teaching practice system include the following parts: camera, TV modulator, mixer, RFamplifier, VCO, phase lock loop, antenna, intermediate frequency amplifier, image demodulator, display, 10 dB directional coupling can form a video image transmission system. Image signal after amplitude modulation (am) and the frequency conversion, the antenna launch out, the image signal by receiving after demodulation can let a person intuitive, real-time see clear image. At the same time, the system of single module can also be used to design students experimental validation and students' secondary development, therefore, this system not only pay attention to the cultivation of students' theoretical knowledge more attention to the beginning ability training.

RF teaching practice system adopts the modular structure design, flexible connection mode for training of experimental training provides a very convenient, flexible assembly, satisfied the various institutions of the experimental teaching requirements, and more exercise the student's beginning ability, thinking ability and innovation ability, in addition, the system module circuit all adopt the microstrip circuit design, can be clearly observed all microstrip circuit structure; Transparent organic glass plate application, make each module legerity, beautiful, and can be integrated in an instrument box, easy to carry and transportation.
