mmWave Spatial–Temporal Single Harmonic Switching Transmitter Arrays for High Back-Off Beamforming Efficiency
This article presents a spatial–temporal single harmonic switching (STHS) transmitter array architecture with enhanced efficiency in the power back-off (PBO) region. STHS is an electromagnetic circuit co-designed and jointly optimized transmitter array that realizes beamforming and back-off power generation at the same time. The temporal dimension is originally added in …
