For FDD operation the TRX supports a lowIF mode that meets the dynamic range requirements of GSM basestations. It provides full-band multicarrier (MC) operation in all TDD/FDD 3GPP bands for 2G/3G/4G/5G radios. The SoC includes an 8×16Gb/s SERDES interface, two receivers, two transmitters, and a digital pre-distortion (DPD) feedback RX (FBRX) (Fig. 9.3.1). The FBRX employs a “stitching” system that combines the outputs
