该论文提出一种瞬时宽带超紧凑高线性功率放大器，采用补偿分布式巴伦输出网络，以实现5G毫米波频段（如n257、n258、n260）的多频段覆盖。解决了传统PA在宽带、高线性与紧凑尺寸之间的折衷问题。
5G communication promises 10× to 100× data-rate increase to radically change future wireless connectivity. Millimeter-wave (mm-wave) bands can potentially deliver extreme data rates and capacity compared to low-GHz bands. The 3GPP 5G NR standard specifies n257 band (26.50 to 29.50GHz), n258 band (24.25 to 27.50GHz), and n260 band (37.00 to 40.00GHz) for Frequency Range 2 (FR2) [1]. Different FR2 bands or their subsets are adopted by various countries/regions worldwide, which necessitates wideband/multiband mm-wave 5G systems to support international/cross-network roaming, particularly for user equipment (UE) devices [2,3]. Common wideband power-amplifier (PA) architectures often suffer from various limitations [4]. Balanced PAs require wideband 90° hybrids that are often bulky and lossy for on-chip implementation. Staggered tuning sacrifices PA gain and output power (Pout). High-order matching networks are popular for
