10.6 A 4G/5G Cellular Transmitter in 12nm FinFET with Harmonic Rejection

5G New Radio (NR) technology provides much higher data rate and system capacity compared to 4G LTE. This is achieved, among other techniques, by increasing the maximum channel bandwidth per component carrier (CC) from 20MHz in LTE to 100 MHz in NR and by introducing new frequency bands in the range of 3.3 to 5GHz [1]. A 4G/5G multimode multiband cellular transceiver must support this wide bandwidth and wide tuning range while maintaining excellent EVM for high-order modulation and high linearity and low noise for challenging LTE scenarios.
