Summary:As the millimeter-wave (mm-wave) spectrum is believed to drive the next wireless communication revolution, there is a growing need for architectural research on advanced transmitter (TX) or power amplifier (PA) that can radically push the performance envelope of mm-wave power amplification to the next level [1]. This is especially true for future mm-wave 5G deployment that extensively employs high peak-to-average power ratio (PAPR) waveforms and poses demanding TXs/PAs requirements, including linearity, peak efficiency, power back-off (PBO) efficiency, and capability of supporting multi-Gb/s modulation [2-7].
