Abstract
A scalable N×N single-chip dual-band MIMO RF transceiver module compatible with the IEEE 802.11n standard for WLAN applications is provided. A modular design approach allows a transceiver of substantially any dimension to be created on a single chip that may be easily integrated with other system components. An N×N MIMO transceiver module includes N substantially identical transceiver blocks and a common local oscillator. Each transceiver block includes transmitters and receivers for transmitting and receiving signals in two distinct frequency bands. The transceiver blocks further include one or more local oscillator signal repeaters for receiving one or more local oscillator signals and forwarding the one or more local oscillator signals to subsequent transceiver blocks.
