Dual-band CMOS transceiver with highly integrated front-end for 450Mb/s 802.11n systems

A 3-stream, 802.11n WLAN MIMO transceiver, with fully integrated PAs and LNAs in both 2.4GHz and 5GHz bands, and a T/R switch in the 2.4GHz band, was implemented in a standard 90nm CMOS technology. The transmitter achieves an EVM of -28dB at output power of 19dBm and 17dBm in the 2.4GHz and 5GHz ban...

More Information
Summary:A 3-stream, 802.11n WLAN MIMO transceiver, with fully integrated PAs and LNAs in both 2.4GHz and 5GHz bands, and a T/R switch in the 2.4GHz band, was implemented in a standard 90nm CMOS technology. The transmitter achieves an EVM of -28dB at output power of 19dBm and 17dBm in the 2.4GHz and 5GHz bands, respectively. The transmitter power consumption per Mb of data, in 3-stream mode, is 3.7mW/Mb and 4.5mW/Mb in the 2.4GHz and 5GHz, respectively. This is four times lower comparing to the single stream (SISO) mode. The receiver NF is 4dB in both bands, and power consumption is 1.6mW/Mb and 1.7mW/Mb, in the 2.4GHz and 5GHz bands, respectively.
