MULTI-CHANNEL CORRECTION APPARATUS, MULTI-CHANNEL CORRECTION METHOD AND TRANSCEIVING SYSTEM

摘要

This application relates to the antenna communications field, and provides a multi-channel calibration apparatus, an amplitude calibration method, a phase calibration method, a transceiver system to reduce design complexity and implementation complexity of a high frequency circuit in a calibration feed network. In the calibration apparatus, a calibration feed unit includes a plurality of conversion units. The conversion units act as detectors on transmit channels, and act as reference source units on receive channels. Because a conversion unit can directly connect a channel to a calibration control unit, and two adjacent conversion units are jointly coupled to one channel, the channel to which the adjacent conversion units are jointly coupled can be used as a basis in a calibration to implement a multi-channel calibration. Therefore, there is no need to cascade the conversion units, and complexity of the calibration feed network is greatly reduced.
