Editorial Summary :

Researchers from Tokyo Institute of Technology have developed a novel phased-array beamformer for 5G base stations . The New Radio (NR) 39 GHz band is allocated to 5G networks but not effectively utilized owing to technological limitations . The researchers will present their findings in the upcoming 2022 IEEE Symposium on VLSI Technology and Circuits . The team at Tokyo Tech modified the conventional Doherty amplifier design and produced a bi-directional amplifier . This means that the same circuit can amplify a signal to be transmitted and a received signal with low noise . The proposed device compensates the inter-element mismatches in the shared-LUT DPD module . “Hopefully, the device and techniques described in this study will let us all reap the benefits of 5G NR sooner,” says Professor Okada . “We hope to be able to use the technology sooner,” he says of the proposed device and the techniques described by the study . The study was published on Tuesday in Japan’s The Japan Institute of Science & Technology for 5G Network Network .
