As a new type of high-frequency band resource,terahertz wave has a higher carrier frequency,it can withstand larger bandwidth and transmission rate,therefore,it has become a research hotspot for new generation broadband communications.A 300 GHz terahertz wireless communication system is constructed based on pure electronic devices,in which the transmitter has a simple structure and the whole system is less complex than the photon-assisted system.Signal transmission experiments with wireless distances of 50 m and 100 m are conducted.The transmission performance of the system is explored and the relationships among the transmission performance,transmission rate and transmitting voltage are studied.As far as we know,100 m is the longest distance that an all-electronic terahertz wireless transmission system can achieve without using a Power Amplifier(PA).
