Abstract :
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.
