Product Description

With the development of electronic industry, especially for the third-generation mobile communication technology, the field of high-frequency circuit design is received high attention within industry. Such courses as High-frequency Electronic Circuit, Radio Frequency Communication Circuit, Electromagnetic Field and Electromagnetic Wave, Antenna and Electric Wave Transmission, Microwave Communication are regarded as compulsory courses for students on Communication & Electronic majors among colleges and universities. Such courses are always thought difficult for students, in addition, the experiment methods are shortage, and therefore, radio frequency circuit design has been the weakest link in the teaching of Communication & Electronic majors. If build radio frequency communication lab according to traditional methods, it needs to configure a large quantity of high-grade test apparatuses, such as network analyzer, spectrum analyzer and digital oscilloscope over 500M. The cost is too much for colleges and universities; Therefore it causes difficulty in building lab.
