A Superheterodyne 300 GHz Wireless Link for Ultra-Fast Terahertz Communication Systems

This paper presents an all-electronic superheterodyne wireless system based on millimeterwave monolithic integrated circuits at a center frequency of 300 GHz. Superheterodyne operation is attractive for compliance with the recent IEEE802.15.3d frequency standard. The super-heterodyne transmission is realized, both, with mixers operating at a frequency of 10 GHz, and with an arbitrary waveform generator output centered around 10 GHz. The paper compares both options in terms of error vector magnitude for different baud rates and modulation formats. Data rates of up to 60 Gbps and distances of up to 10 meters are achieved using complex modulated signals like 16-QAM and 32-QAM.
