“…Compared to implementations in other technologies, e.g. GaAs mHEMTs, with CLs of 11.4 dB [12] the CL of the demonstrated GFET receiver is still higher. However, the simulations show, that development and optimization of the GFETs and passive components will allow for further improvement of the receiver performance.…”

A receiver composed by a graphene FET 200-GHz mixer and a 1-GHz intermediate frequency amplifier integrated on a silicon substrate was modelled, fabricated and characterized. This is the first demonstration of a millimeter wave integrated receiver based on graphene FETs. The receiver conversion loss is measured to be 25 dB across the 185-205-GHz band with 16 dBm of local oscillator pump power, which is in good agreement with the circuit simulations. The simulations show that the receiver conversion loss can be significantly reduced to 16 dB by reducing the contact resistance and by realizing a higher charge carrier mobility in the mixer transistor.

“…The RF system consists of a 300 GHz transmitter and receiver based on monolithic millimeterwave integrated circuit (MMIC) packaged in split-block waveguide modules with a WR-3 output at the RF port and a WR-12 at the LO input. The MMICs have been described in detail in [12] and are fabricated in a 35nm metamorphic high electron mobility transistor (mHEMT) InGaAs technology with a maximum oscillation frequency above 1 THz and a maximum transit frequency of above 500 GHz [13]. Figure 3 shows the schematic of the active electronic transmitter and receiver MMICs.…”

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The second involves the usage of commercially available mixers, which work as direct up- and down-converters, to generate the IF input and output. The radio frequency components are based on millimeterwave monolithic integrated circuits at a center frequency of 300 GHz. Transmission experiments over distances up to 10 m are carried out. Data rates of up to 60 Gbps using the first IF option and up to 24 Gbps using the second IF option are achieved. Modulation formats up to 32QAM are successfully transmitted. The linearity of this link and of its components is analyzed in detail. Two local oscillators (LOs), a photonics-based source and a commercially available electronic source are employed and compared. This work validates the concept of superheterodyne architecture for integration in a beyond-5G network, supplying important guidelines that have to be taken into account in the design steps of a future wireless system.

“…In the recent past many research groups all over the globe have made significant progress in developing RF front ends and antennas enabling wireless data transmission at 300 GHz and beyond. Whereas at the receiving end of a link electronic approaches using mostly Schottky-Barrier Diodes are used, for the generation of the signals at the transmitting end both photonic [7,8] and electronic [4,19] approaches have been applied. Wireless data rates of 100 Gbit/s and beyond have been demonstrated, see e. g. [5].…”

Already a couple of years ago THz communications have not only become an attractive new research area on channel modeling but also triggered a couple of projects heading to develop appropriate technological solutions to enable the setup of hardware demonstrators. Also discussions and activities in standardization and regulation already took off. In October 2017, IEEE published Std. IEEE 802.15.3d-2017 the worldwide first wireless communications standard operating in the 300 GHz frequency band. In parallel to the standardization process activities at the ITU-R level targeting on the provision of an appropriate regulatory framework at the World Radio Conference 2019 (WRC-2019) via a dedicated agenda item have taken off. This paper provides a brief overview on the current status of the development of THz Communication systems focusing on recent results on advanced channel characterization at 300 GHz, hardware demonstrators operating in this frequency range, the past and current activities at IEEE 802 and the WRC 2019 preparations.
