MIMO Transceiver with AFE 76 xx for LTE and 5 G Wireless Radio

ABSTRACT In this application report, the implementation and performance of a radio transceiver suitable for multipleinput multiple-output (MIMO) wireless communications will be presented. AFE76xx is the main device used for the transceiver design. This device integrates 4 analog-to-digital converters (ADCs), 4 digital-toanalog converters (DACs) and a phase-locked loop (PLL) for sampling clock generation. The main advantage of this MIMO transceiver implementation is the high level of integration, which makes it easier to expand to larger antenna arrays via synchronization of multiple AFE76xx devices. Also the direct RFsampling based data converters eliminate common analog impairments in radio transceiver design such as local oscillator (LO) leakage and sideband image.
