Mobile cellular subscribers reached more than 6 billion in 2021, and 5G LTE brings high data capacity as low latency using sub-6GHz and mm-Wave spectrum. There is a partitioning for which RF blocks are placed into CMOS advanced nodes and which blocks are left in the RF front end module (RFFEMs). RF front end modules are controlled by MIPI RFFE℠, and this presentation covers the challenges for this control with exemplifications.
