ABSTRACT:
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.
