Abstract: We present an RF-DAC-based transmitter that uses an expanding characteristic to linearize the PA. Implemented in 22nm FDSOI CMOS, the transmitter operates with a carrier frequency of 12.5GHz, achieving a sample rate of 7GS/s. Measurements with >3.5GSym/s wideband modulated 64QAM SC and OFDM signals show EVMRMS0.6 percent unit EVM improvement and a >2.5dB ACPR improvement are observed.
