Abstract

A multi-chain tester is disposed on a substrate for testing multi input multi output (MIMO) devices. The multi-chain tester includes a first attenuation circuit, a switch circuit, a controlling circuit and a divider circuit. The first attenuation circuit electronically connected to the MIMO device is used for tuning the resistance of the multi-chain tester. The switch circuit electronically connected the first attenuation circuit. The controlling circuit electronically connected to the switch circuit for controlling the switch circuit. The divider circuit electronically connected to the switch circuit is used for sending electronic signals that sent by the MIMO device through the switch circuit and the first attenuation circuit to at least one test device to test the communication parameters of the MIMO device.
