Abstract

This work describes a compact

$2\times 16$

-channel phased-array transceiver IC designed for millimeter-wave (mm-Wave) applications over 24.25–29.5 GHz, fabricated using 45 nm radio frequency silicon-on-insulator (RFSOI) CMOS technology. The design achieves high RF performance and occupies a compact die area. It features a Doherty power amplifier (PA) that achieves a high linear output power (POUT) of 14.5 dBm at a third-order intermodulation distortion (IMD3) of -25 dBc, as well as a compact low-noise amplifier (LNA) with a wide-band noise figure (NF) below 2.75 dB over the operating frequency range. In transmitter (TX) mode, the transceiver IC delivers an average POUT greater than 11.0 dBm/Ch., with an error vector magnitude (EVM) of -25 dB, while consuming less than 155 mW/Ch. In receiver (RX) mode, it records an NF ranging from 3.2 to 3.7 dB, with power consumption below 48.8 mW/Ch. The entire size of the transceiver IC is 59.8 mm2, with each channel occupying a die area of 1.87 mm2.

基于45nm RFSOI CMOS的大规模、低功耗、紧凑型5G毫米波相控阵收发器

这项工作描述了一种紧凑的2 × 16通道相控阵收发器IC，设计用于24.25-29.5 GHz的毫米波（mm-Wave）应用，采用45 nm射频绝缘体上硅（RFSOI） CMOS技术制造。该设计实现了高射频性能，并占用了紧凑的模具面积。它具有一个Doherty功率放大器（PA），在三阶互调失真（IMD3）为-25 dBc时实现14.5 dBm的高线性输出功率（POUT），以及一个紧凑型低噪声放大器（LNA），在工作频率范围内宽带噪声系数（NF）低于2.75 dB。在发送器（TX）模式下，收发器IC提供的平均POUT大于11.0 dBm/Ch。，误差矢量幅度（EVM）为-25 dB，而功耗低于155 mW/Ch。在接收器（RX）模式下，它记录的NF范围为3.2至3.7 dB，功耗低于48.8 mW/Ch。收发器IC的整体尺寸为59.8 mm2，每个通道占用1.87 mm2的芯片面积。

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
