“…In order to realize a 300 GHz transceiver in a CMOS integrated circuit, these architectures need to be combined. Figure 9 shows the architecture of a 300 GHz CMOS transceiver [29,30]. A rat-race circuit is used for the power coupling required for the transmitter and receiver, respectively.…”

A 44 GHz frequency band from 252 GHz to 296 GHz has been identified for communications. This frequency band is part of the 300 GHz band, which is expected to be utilized for ultra-high speed wireless communication toward 6G. In this letter, we will discuss the requirements for ultra-wideband wireless communications in the subterahertz range, including the 300 GHz band, and clarify the necessity of a communication system based on phased arrays. Finally, a 300 GHz CMOS wireless transceiver capable of transmitting data rates of up to 80 Gb/s that can be utilized as an element of this phased array is presented.

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.

“…Before beginning a discussion of these technologies we present Table 1 that summarizes some of the forefront technologies and their performance metrics. Complementary metal-oxide-semiconductor (CMOS) circuits are increasingly becoming a legitimate and competitive approach for implementing terahertz communication technologies up to about 300 GHz [61][62][63][64], with the potential benefits of low cost and easy integrability into modern digital electronics. This is particularly true for mobile devices.…”

A Perspective on Terahertz Next-Generation Wireless Communications

In the past year, fifth-generation (5G) wireless technology has seen dramatic growth, spurred on by the continuing demand for faster data communications with lower latency. At the same time, many researchers argue that 5G will be inadequate in a short time, given the explosive growth of machine connectivity, such as the Internet-of-Things (IoT). This has prompted many to question what comes after 5G. The obvious answer is sixth-generation (6G), however, the substance of 6G is still very much undefined, leaving much to the imagination in terms of real-world implementation. What is clear, however, is that the next generation will likely involve the use of terahertz frequency (0.1–10 THz) electromagnetic waves. Here, we review recent research in terahertz wireless communications and technology, focusing on three broad topic classes: the terahertz channel, terahertz devices, and space-based terahertz system considerations. In all of these, we describe the nature of the research, the specific challenges involved, and current research findings. We conclude by providing a brief perspective on the path forward.
