Designed for space application, the paper presents the design, test and application of the front end in 0.3THz wireless communication. After test and fabrication, the terahertz wireless system is completed and indicates that HD video signals have been transmitted over a distance of 14m at the data rate of 1.5Gbps. The study shows the overall course of the test and application of the front end in wireless communication.

Contrary to the terahertz (THz) applications on the ground, the space applications in the atmosphere free environment do not suffer the atmosphere attenuation. In this study, a 0.3 THz wireless communication systems designed for potential space applications has been set up. It consists of transmitter and detector units based on Schottky diode mixers technology. The system performance is shown including the received signal levels and Eb/N0. For demonstration of THz communications, HD video signals have been transmitted over a distance of 14 m at the data rate of 1.5Gbps.
