Abstract

In this letter, a second harmonic suppressed millimeter-wave (mm-wave) gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifier (PA) using the self-resonate characteristic of the capacitor is proposed. Based on a simple modified band-pass output matching network, a novel second harmonic suppression method by utilizing the self-resonate characteristic of the on-chip capacitor is proposed, which can realize the harmonic suppression without any additional tuning structures. For verification, a 24-to-28-GHz GaN MMIC PA was designed using a 150-nm GaN on silicon carbide high electron mobility transistor process. The fabricated PA achieved a saturated power range of 32.5-34 dBm, with a corresponding power-added efficiency (PAE) of 37.5%-44.5%. The amplifier achieved good linearity when excited by a 400-MHz orthogonal frequency division multiplexing signal after applying digital predistortion.

利用电容的自谐振特性抑制二次谐波的毫米波GaN MMIC功率放大器

本文提出了一种利用电容自谐振特性的二谐波抑制毫米波(mm-wave)氮化镓(GaN)单片微波集成电路(MMIC)功率放大器。基于一种简单的改进带通输出匹配网络，提出了一种利用片上电容自谐振特性的二次谐波抑制方法，该方法无需额外的调谐结构即可实现谐波抑制。为了验证这一点，我们采用150纳米碳化硅高电子迁移率晶体管工艺设计了24 ~ 28 ghz GaN MMIC放大器。所制备的PA达到了32.5-34 dBm的饱和功率范围，相应的功率附加效率(PAE)为37.5%-44.5%。采用数字预失真后，在400 mhz正交频分复用信号的激励下，放大器获得了良好的线性度。
