Abstract :
A single-chip multi-band direct-conversion CMOS MIMO transceiver (2 times 2) targeted for WLAN applications is presented. This transceiver is capable of satisfying the requirements of the Enhanced Wireless Consortium and achieves PHY rates of >270Mb/s. The receivers and transmitters achieve an EVM of better than -41 dB (0.9%) and -40dB (1.0%) operating in legacy g and a modes, respectively. From a 1.8V supply and with both cores operating, the chip draws 275mA in RX mode and 280mA in TX mode.
