摘要

本文提出了一种采用新型补偿技术的4.5-5.5 GHz宽带高效Doherty功率放大器(DPA) MMIC。对载波和峰值放大器的相位差和输出电容进行了分析，并在宽带范围内进行了精确的补偿。因此，在宽带中获得了DPA的充分负载调制。为了验证所提出的设计方法，在0.25µm GaN-HEMT工艺中设计和制造了宽带高效DPA MMIC，用于5G大规模MIMO应用。测量结果表明，在饱和输出功率(Psat)为39.8 ~ 40.8 dBm时，功率附加效率(PAE)为44.8% ~ 52.2%，在6 db输出回退(OBO)时，PAE为40.9% ~ 43.9%，小信号增益为12.5 ~ 13.9 db。所提出的DPA在已发布的c波段宽带GaN MMIC DPA中展示了最先进的饱和和6db回退PAE。

A fully integrated wideband GaN Doherty power amplifier MMIC with high efficiency for 5G massive MIMO application

In this paper, a 4.5-5.5 GHz wideband high efficiency Doherty power amplifier (DPA) MMIC using a novel compensation technique is proposed. The phase difference and output capacitances of the carrier and peaking PA are analyzed and compensated accurately in a wideband. Thus a sufficient load modulation of the DPA is obtained in a broadband. To verify the proposed design methodology, a broadband high-efficiency DPA MMIC is designed and fabricated in a 0.25 µm GaN-HEMT process for 5G massive MIMO applications. The measurement results illustrate that power added efficiency (PAE) is 44.8%-52.2% at the saturated output power (Psat) of 39.8-40.8 dBm, the PAE at 6-dB output back-off (OBO) is 40.9%-43.9%, and the small-signal gain is 12.5-13.9dB. The proposed DPA demonstrates state-of-the-art saturated and 6-dB back-off PAE among published C-band broadband GaN MMIC DPAs.
