TL;DR: In this article, a 120-GHz-band wireless link that uses millimeter-wave photonic techniques was developed, which achieved error-free transmission of OC-192 and 10-GbE signals over a distance of more than 200 m with a received power of below -30 dBm.

TL;DR: In this paper, the authors investigated the maximum output power of these devices and compared the phase noise of MMW signals generated by high-speed uni-traveling carrier photodiodes (UTC-PD) and InP high-electron mobility transistor (HEMT) millimeter-wave (MMW) monolithic integrated circuits (MMICs).

TL;DR: In this article, the authors proposed a solution to provide bioelectric-signal monitor clothing compatibly attaining a decrease in a wearing burden and improvement in a reception quality of bioelectric signals, while securing a degree of adhesion of a human body and bioelectrodes.

TL;DR: A rectangular-waveguide output UTC-PD module integrating a HEMT power amplifier has been developed for operation in the 125-GHz band and exhibits maximum output power of more than 14 dBm with nearly flat frequency dependence.

TL;DR: A 10-Gb/s wireless link system that uses a 120-GHz-band sub-terahertz electro-magnetic waves and is composed of all-electronic devices using InP-HEMTs is presented.
