A 57-71 GHz Beamforming SiGe Transceiver for 802.11 ad-Based Fixed Wireless Access

Abstract

A beamforming transceiver for 802.11ad-based wireless access applications manufactured in a f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> /f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> = 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.
