摘要：A device and method for calibrating MIMO systems are disclod. In one aspect,a calibration circuit compris at least a first and a cond input/output port, each
arranged for being connected to a different transmitter/receiver pair of a multiple input
multiple output (MIMO) system. The circuit further compris at least a third and a fourth input/output port, each arranged for being connected to a different antenna. The circuit further compris an attenuator having a first attenuator port and a cond attenuator port. The circuit further compris a first and a cond non-reciprocal switch, the first switch being arranged for establishing a connection between the first
input/output port and either the third input/output port or the first attenuator port, and the cond switch arranged for establishing a connection between the cond
