摘要： A method and apparatus for controlling a multi-input multi-output (MIMO) radio frequency (RF) transceiver having a plurality of RF blocks using a single serial programming interface (SPI) are provided. The MIMO system includes: a MIMO transceiver, having one or more input and output units and a serial interface conversion unit controlling the input and output units; and a controller, which controls the MIMO transceiver. The serial interface conversion unit receives control data from the controller via a serial programming interface (SPI), decodes the received control data to have a format appropriate for controlling the input and output units, and encodes data received from the input and output units to be compatible with the SPI. Accordingly, it is possible to realize a small-sized MIMO system having a simple structure and to reduce the probability of errors occurring in the process of controlling a plurality of RF blocks of the MIMO system.

摘要： A transceiver device capable of calibration, and a calibration method used by the transceiver device. The transceiver device includes a reference transceiver, a plurality of remaining transceivers, and a plurality of transmission calibration paths connecting the remaining transceivers to the reference transceiver for transmission calibration of the remaining transceivers. An envelope detector included in the reference transceiver is shared with the remaining transceivers. When implementing a multiple input multiple output (MIMO) transceiver in a single chip, the chip size and manufacturing cost of the MIMO transceiver device can be substantially reduced.
