This article presents the 38-GHz phased array 32-element Tx and 16-element Rx with 2-GHz IF and 5-GHz LO for fifth-generation (5G) millimeter-wave (MMW) communications. The Tx and Rx beamformers and upconverters/downconverters are fabricated in 65-nm CMOS. The PAs and LNAs near antenna ends are fabricated in 0.15- $\mu \text{m}$ GaAs pHEMT. The eight-element Tx and four-element Rx phased array printed circuit board (PCB) modules integrated with multiple integrated circuits (ICs) and endfire antennas are implemented as unit cells. Four pieces of Tx modules are vertically stacked to construct an $8\times {4}$ brick array (planar array), while four Rx modules are to construct a $4\times {4}$ array. According to 38-GHz over-the-air (OTA) measurements, the 32-element Tx shows 47.5-dBm equivalent isotropic radiated power (EIRP) at OP $_{\mathrm {1 ~dB}}$ with −35.2-dB image rejection ratio (IMRR) and −37.4-dB $\times 8$ LORR. The 16-element Rx at 38 GHz shows −4-dBm OP $_{\mathrm {1~dB}}$ with −28-dB IMRR and −36.6-dB LORR. The Tx and Rx support the beam scanning around ±60° azimuth and ±30° elevation planes. The Tx-to-Rx wireless data link demonstrates 64 quadrature amplitude modulation (QAM)/400 M-BR, 256 QAM/200 M-BR, and 512 QAM/100 M-BR in 20 m. To the best of our knowledge, this work is the first 5G 37-/39-GHz phased array Tx/Rx using the scalable brick array configuration and demonstrating competitive performances compared with previous works.

基于可扩展相控阵模块的 38 GHz 相控阵发射器和接收器,带有用于 5G MMW 数据链路的端射天线阵列

本文介绍了用于第五代 (5G) 毫米波 (MMW) 通信的 38 GHz 相控阵 32 单元 Tx 和 16 单元 Rx,具有 2 GHz IF 和 5 GHz LO。Tx 和 Rx 波束形成器和上变频器/下变频器采用 65-nm CMOS 制造。天线末端附近的 PA 和 LNA 采用 0.15- $\mu \text{m}$ GaAs pHEMT。与多个集成电路 (IC) 和端射天线集成的八元件 Tx 和四元件 Rx 相控阵印刷电路板 (PCB) 模块作为单元实现。四块 Tx 模块垂直堆叠以构建一个 $8\times {4}$ 砖阵列(平面阵列),而四个 Rx 模块将构建一个 $4\times {4}$ 大批。根据 38-GHz 空中 (OTA) 测量,32 单元 Tx 在 OP 处显示 47.5-dBm 等效全向辐射功率 (EIRP) $_{\mathrm {1 ~dB}}$ 具有 −35.2-dB 镜像抑制比 (IMRR) 和 −37.4-dB $\times 8$ 洛尔。38 GHz 下的 16 单元 Rx 显示 −4-dBm OP $_{\mathrm {1~dB}}$ 具有 −28-dB IMRR 和 −36.6-dB LORR。Tx 和 Rx 支持围绕 ±60° 方位角和 ±30° 仰角平面进行波束扫描。Tx-to-Rx 无线数据链路在 20 m 内展示了 64 个正交幅度调制 (QAM)/400 M-BR、256 QAM/200 M-BR 和 512 QAM/100 M-BR。据我们所知,这项工作是第一个使用可扩展砖阵列配置的 5G 37-/39-GHz 相控阵 Tx/Rx,与之前的工作相比,展示了具有竞争力的性能。
