Mo2B-3 : A D-Band Radio-on-Glass Module for Spectrally-Efficient and Low-Cost Wireless Backhaul
D-Band Radio-on-Glass (RoG) modules combining two highly integrated SiGe BiCMOS transceivers (TRX) with a record low-loss glass interposer technology are presented. The ICs operate at 115–155 GHz (Low-Band) and 135–170 GHz (High-Band). In this frequency range, a transmitter Psat up to 13 dBm and an average receiver NF of 8.5 dB is achieved. The integrated module supports TX constellations up to 512-QAM (2.2% EVM at 2 dBm output, 145 GHz) and data-rates up to 42 Gb/s (128-QAM). Measurements mimicking a 250-meter wireless-link demonstrate a maximum data-rate of 36 Gb/s using 64-QAM. The RoG modules represent the first low-cost and highly integrated solution for spectrally efficient backhaul systems in D-Band.
