Abstract

This paper presents an ultra-wideband (UWB) medium power amplifier (MPA) and a broadband high-power power amplifier (HPA) operating at the 5G/6G frequency bands. By using

$0.15~\mu \text{m}$

GaAs pseudomorphic high electron mobility transistor (pHEMT) technology process, the proposed UWB MPA delivers an average small-signal gain of 16.5 dB, a saturation output power (

$\text{P}_{\mathrm {sat}}$

) of 24 dBm, and a peak power-added efficiency (PAE) over 24% from 24 to 38 GHz with a chip area of

$2\times1$

mm2. The broadband HPA demonstrates a 17-dB average small-signal gain, 29-dBm

$\text{P}_{\mathrm {sat}}$

, and a PAE over 28% from 24 to 32 GHz with a

$2.4\times1.1$

mm2 chip size. The measurement results have demonstrated the great potential of the proposed PA for 5G/6G millimeter-wave applications.

用于 5G/6G 应用的毫米波砷化镓超宽带中功率放大器和宽带大功率放大器

本文介绍了一种超宽带（UWB）中功率放大器（MPA）和一种工作在 5G/6G 频段的宽带大功率放大器（HPA）。通过采用 0.15~\mu \text{m}$ GaAs 伪态高电子迁移率晶体管 (pHEMT) 技术工艺，所提出的 UWB MPA 实现了 16.5 dB 的平均小信号增益、24 dBm 的饱和输出功率（$\text{P}_{\mathrm {sat}}$）以及 24 至 38 GHz 超过 24% 的峰值功率附加效率（PAE），芯片面积为 2\times1$ mm2。宽带 HPA 的平均小信号增益为 17dB，$text{P}_{\mathrm {sat}}$ 为 29dBm，24 至 32 GHz 的 PAE 超过 28%，芯片面积为 2.4times1.1mm2 美元。测量结果证明了所提出的功率放大器在 5G/6G 毫米波应用中的巨大潜力。
