3GHz RF educational training system

I.Overview

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. 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 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.

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. 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. 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.

And other radio frequency and microwave experiment system is different, this training system mainly based on frequency domain technology and spectrum measuring instrument. To do so mainly has the following two considerations: first of all, the radio frequency communication, sensor, signal processing such as the most important sector, the frequency domain contains a lot of inconvenience in time domain or is difficult to measure the important information, by the use of high sensitivity and wide dynamic range of spectrum analyzer, Can be very convenient measuring low level amplitude modulation, frequency modulation and pulsed radio frequency signal. And can be used to measure the carrier frequency, modulation frequency, modulation level and modulation distortion; Also can easily detect converter pieces of frequency conversion loss, isolation degree and distortion characteristics;
