摘要

在这项工作中，我们提出了一种基于90nm SiGe技术的高效宽带毫米波功率放大器(mm-wave PA)设计，用于潜在的5G应用。布局后提取仿真结果表明，该放大器在24-32.5 GHz频段实现了宽带功率附加效率(PAE) >31.4%，增益>8.5 dB, POUT,sat >13.3 dBm，在26 GHz频段峰值PAE为40.2%。该放大器在16-QAM LTE 250 MHz调制信号输入下表现出良好的线性度，在26 GHz时获得-38.6/-37.3 dBc的ACLR1, POUT,avg为6.4 dBm。该放大器还具有抗偏置VB = 0.83-0.85 V和电源VCC = 1.0-1.4 V变化的鲁棒性，可适用于多频段5G应用。

A Highly Efficient Broadband mm-Wave 24-32.5 GHz SiGe PA for Potential 5G Applications

We present in this work a highly efficient broadband millimeter-wave power amplifier (mm-wave PA) design in a 90nm SiGe technology for potential 5G applications. The post-layout extraction simulations suggest that the PA achieves broadband power-added efficiency (PAE) >31.4%, gain >8.5 dB, and POUT,sat >13.3 dBm across 24-32.5 GHz, with peak PAE of 40.2% at 26 GHz. The PA shows good linearity with 16-QAM LTE 250 MHz modulated signal input, obtaining ACLR1 of -38.6/-37.3 dBc at 26 GHz with POUT,avg of 6.4 dBm. The PA is also robust against variation in bias VB = 0.83-0.85 V and supply VCC = 1.0-1.4 V and can be applicable toward multi-band 5G applications.
