This work presents a dual-band polar digital transmitter (P-DTX) based on a digitally controlled two-point edge interpolation digital-to-time converter, which is capable of supporting Wi-Fi 6 applications. The proposed P-DTX is fabricated in a standard 28-nm CMOS process. The 2.5/5GHz digital power amplifiers (DPAs) reach a maximum power ($P_{\mathrm {MAX}}$)/power efficiency (PE) of 27 dBm/53% and 27dBm/37%, respectively. The transmitter meets an error vector magnitude (EVM)/DPA PE/total TX power dissipation of −30.5 dB/33%/532 mW for the low band and −29 dB/26%/718 mW for the high band at 6-dB backoff (dBBO) from $P_{MAX}$. An EVM as low as −40 dB is achieved using digital pre-distortion at 7–8 dBBO, for 20–160-MHz signal bandwidths, thus demonstrating MCS11 1024-QAM OFDM Wi-Fi 6 operation. [ABSTRACT FROM AUTHOR] |
