Beschreibungen/Notizen

• 802.11n is the latest offering from the IEEE standard committee tasked with enabling and enhancing WLAN systems. This standard utilizes several techniques to offer a much larger rate versus range than the legacy WLAN systems. A single-chip multiband direct-conversion CMOS MIMO transceiver (2times2) targeted for WLAN applications is presented. This transceiver is capable of satisfying the requirements of the draft 802.1 In standard and achieves PHY rates of > 270 Mb/s. The receivers and transmitters achieve an EVM of better than -41 dB (0.9%) and -40 dB (1.0%) operating in legacy g and a modes, respectively. From a 1.8 V supply and with both cores operating, the chip draws 275 mA in RX mode and 280 mA in TX mode.
