A fully integrated multi-band MIMO WLAN transceiver RFIC

A multiple input multiple output transceiver compliant with IEEE 802.11a/b/g and Japan wireless LAN standards is presented. The transceiver has two complete radio paths integrated on the same chip. When two chips are used in tandem to form a four path composite beam forming system, 15dB of link margin improvement is obtained. The transceiver was implemented in a 47GHz SiGe technology and consumes 195mA in RX mode and 240mA in TX mode from a 2.75V supply

A fully integrated multiband MIMO WLAN transceiver RFIC

A multiple-input/multiple-output (MIMO) transceiver RFIC compliant with IEEE 802.11a/b/g and Japan wireless LAN (WLAN) standards is presented. The transceiver has two complete radio paths integrated on the same chip. When two chips are used in tandem to form a four-path composite beam forming (CBF) system, 15 dB of link margin improvement is obtained. The transceiver was implemented in a 47-GHz SiGe technology with 29.1-mm2 die size. It consumes 195 mA in RX mode and 240 mA in TX mode from a 2.75-V supply
