A direct-conversion transmitter for small-cell cellular base stations with integrated digital predistortion in 65nm CMOS
Network densification and FD MIMO in cellular networks require higher levels of base station integration while still meeting stringent performance requirements. We present a monolithic transmitter with integrated digital predistortion and calibration which allows RF agile, multi-carrier operation and enables efficient small cell and FD MIMO systems to be realized below 24dBm/antenna.
