"65nm CMOS based 8 radio frequency elements, each 0.1 mm2 small, -23.5 dB error vector magnitude in 64-quadrature amplitude modulation, record data rates (up to 9.6 Gbps), area efficiency, and beam switching speed... simultaneous send/ receive multiple mm-wave data streams without added hardware... fast-switching phase shifters adjust signal phase within 2.5 ns, clock-based synchronization controlling beam switching timing, enabling support for more data streams simply increasing clock frequency without increasing size"
