摘要

This paper presents a 28nm CMOS wireless connectivity combo IC with a 2x2 reconfigurable WiFi transceiver, and a BT 5.0 slim SOC. The WiFi transceiver can deliver 2G/5G Psat of 26.5/25.5dBm and 2G/5G NF of 3.6/3.8dB respectively, supporting contiguous/non-contiguous 80+80MHz bandwidth with 256-QAM modulation. The integrated slim BT SOC features to support legacy BT spec but also enable BT 5.0 new features, such as 2Mbps low-energy (LE) packet and stable modulation scheme.
