Next-generation Beyond 5G (B5G) / 6G wireless network systems are currently the subject of intensive research and development to keep up with the rapid growth of mobile traffic. We report a high-yield fabrication process of InP-based transistors and Tera-Hertz monolithic ICs (THz-ICs) with 300-GHz operation, which is one of the candidate frequencies for Beyond 5G / 6G network systems. We also introduce InP-THz-ICs (300-GHz power amplifiers and mixers) and demonstrate that they are suitable candidates for B5G/6G.
