MULTI-CHANNEL CALIBRATION APPARATUS, AMPLITUDE CALIBRATION METHOD, PHASE CALIBRATION METHOD, TRANSCEIVER SYSTEM, AND BASE STATION

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.
