Design of electronic subsystems for a 300 GHz wireless communication system

Recently, there has been an increasing interest in the THz gap due to the attractive applications that can be developed. Among these applications, high data rates communication system links get an important relevance due to the potential high bandwidth that can be obtained. In this paper, a frequency tripler and a fourth harmonic mixer for a wireless communication link at 300 GHz has been designed. Conversion Loss (CL) of the tripler is around 15 dB for 65 GHz bandwidth in which the best value is 12 dB for 318 GHz. For the fourth harmonic mixer, the CL obtained is around 18 dB within 41 GHz bandwidth. The best value is 10.2 dB for 301 GHz.
