Recent Progress in Millimeter and Terahertz Wave Integrated Circuit Technologies for Communications and Sensing Applications

摘要

With the possibility of large absolute bandwidths, the millimeter-wave (mmW, 30 to 300 GHz) and Terahertz (THz) frequency range offer opportunities for high resolution sensing and high data-rate wireless communication. Many technologies have been proposed for operation in the mmW and THz frequency range, but for commercial application, they have to be low cost and easy to deploy. In this paper, possible technology candidates are introduced and their characteristics are discussed. The focus is on electronic systems using e.g. transistors compared to photonic systems using devices such as uni-traveling-carrier photo diodes. In the second part of the paper, we present a system for wireless data-transfer in the THz frequency range. It uses resonant tunneling diodes integrated with a Si-lens for radiation. With a demonstrated data-rate of 13 Gbps, it is a candidate for future THz wireless communication systems.
