= 250/340-GHz SiGe BiCMOS technology is presented. The transceiver is equipped with 16+16 separate RX/TX paths and provides more than 20 dBm combined output power and 6 dB NF in the standard 802.11ad 57-66 GHz band, as well as the 66-to-71-GHz extended fixed-wireless access frequency range. A low phase noise of -101 dBc at 1 MHz offset enables the use of up to 10 Gbit/s 128 QAM full-channel and 256 QAM half-channel single-carrier modulation.
