The MMwave Channel Sounder Based on Antenna in Module

The Millimeter-wave (MMwave) and the beamforming technology havs been the key technology of 5G. To solve the difficulty of measuring the beamforming of MMwave and promote the application of the MMwave, this paper used the real example to offer a MMwave channel sounder solution with Antenna in Module (AiM). It describes the solution of AiM and the channel sounder. And give the test experiments of the channel sounder with AiM to prove the validity of the proposed solution.
