Together with the requirement for LTE+NR Dual Connectivity (EN-DC), the transceiver (XCVR) and RF front-end complexity increases dramatically requiring new techniques to maintain a small and costeffective RF implementation. In this work, a 12nm CMOS 2/3/4/5G multi-RAT (Radio Access Technology) XCVR is presented, capable of supporting up to 6
