Considering the high frequency circuit experiment box at present having many defects, a novel experiment system is designed. Modularity method is adopted in this system, which contains nine module circuits. These circuits include small-signal resonance oscillation amplifier, C-class power amplifier, mixer, amplitude modulation, demodulator, frequency modulation and oscillator, frequency discriminator, remote control coding and remote control decoding. The nine modules can carry out experi?ment independently as well as contact each other to develop synthetical experiments more than six. Based on satisfying the basic verifiability experiments, teaching outline is clenched by this system, which extends developable and synthetical experiment great?ly.
