Millimeter-wave/terahertz circuits and transceivers for broadband wireless systems

This paper reviews millimeter-wave and terahertz wireless technological developments in NTT Corporation. We show a 60-GHz band transceiver with low temperature co-fired ceramic-system-in-package modules and MMICs. We also show a 120-GHz band wireless link using InP HEMT MMICs for 120-GHz band, 10-Gb/s broadband wireless link systems.
