By employing spatial diversity, Multi-user MIMO and high-density modulation (up to 256-QAM), 802.11ac MIMO radios can provide significantly increased throughput, link robustness, and range while maintaining backwardcompatibilities with existing 802.11a/n WLAN [1]. However, wide signal bandwidth and high-density modulation lead to significant challenges in all aspects of RF transceiver design, compared to previous WLAN standards. This paper introduces a fully integrated 3-stream MIMO WLAN SoC that integrates all of the functions of an 802.11a/b/g/n/ac WLAN with a record over-the-air TCP/IP
