An 802.11a/b/g/n/ac WLAN Transceiver for $2 \times 2$ MIMO and Simultaneous Dual-Band Operation with +29 Dbm $\text{p}_{\mathrm {sat}}$ Integrated Power Amplifiers

This paper describes the first dual-band MIMO 802.11a/b/g/n/ac WLAN RF transceiver capable of simultaneous dual-band operation. The measured receiver sensitivity of 2 GHz at 54 Mbps is -78.3 dBm and of 5 GHz for VHT80 is -66 dBm. The 802.11ac 2×2 MIMO 20 MHz MCS0 2 GHz and 5 GHz receiver sensitivity levels are -96 dBm and -95.5 dBm respectively. Integrated power amplifiers with Psat of +29 dBm enable the 2 GHz transmitters to achieve TX output power of +23.5 dBm at 54 Mbps 64-QAM. The 5 GHz transmitters achieve +17 dBm output for VHT80 256-QAM. This WLAN-BT connectivity SoC is implemented in 40 nm CMOS technology.
