  • Millimeter-wave MMIC Technologies Exploring F-band Application

    KOSUGI Toshihiko , HIRATA Akihiko , MURATA Koichi , KUKUTSU Naoya , KADO Yuichi , ENOKI Takatomo

    We describe ICs and their waveguide modules for F-band wireless communications and imaging systems. InP-HEMTs and a coplanar waveguide design were employed for the ICs. We achieved error-free transmis …

  • Low-Phase Noise Photonic Millimeter-Wave Generator Using an AWG Integrated with a 3-dB Combiner

    HIRATA Akihiko , TOGO Hiroyoshi , SHIMIZU Naofumi , TAKAHASHI Hiroshi , OKAMOTO Katsunari , NAGATSUMA Tadao

    We present a low-phase-noise and frequency-tunable photonic millimeter-wave (MMW) generator based on two-mode beating. The generator consists of a single-mode laser, an external optical intensity modu …
