This session highlights circuit techniques that advance fully digital PAs and transmitters toward higher output power, broader bandwidth, and cleaner spectra. It begins with a reconfigurable multi-standard IoT digital transmitter using IQ-shared PA. Next, a 28.5 dBm all-digital Wi-Fi 7 polar transmitter employing triple-stacked class-G Doherty PA is demonstrated. The third paper presents a Wi-Fi Doherty polar transmitter that suppresses out-of-channel noise using a mixed-domain FIR technique. The session concludes with a wideband RF power DAC achieving −47.2dB EVM.
