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.
