A design of broadband multiple-input and multiple-output(MIMO) millimeter wave transceiver system is developed in this paper. The millimeter wave(mm-wave) transceiver system includes the ultra-wide bandwidth baseband data processing unit (BAP), intermediate frequency module (IF), mm-wave frontend and the power module. The developed system can support 4×4 MIMO configuration. The mm-wave frequency of...
In this paper, the wideband digital predistortion (DPD) and the Zhu's general sampling theorem (ZGST) are applied to compensate the nonlinear characteristics of a wideband RF power amplifier with memory effects. In order to utilize the ZGST, the DPD test bench is carefully designed after analysis with the ZGST. The power amplifiers are excited by a long term evolution advanced signal with up to 100...
