本文介绍了 60 GHz <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>- 和 <inline-formula> <tex-math notation="LaTeX">$2 \times 256$ </tex-math></inline-formula>-元件双极化双光束晶圆级相控阵收发器，集成了上/下转换器。 <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula> 元件相控阵构建为单个标线并占据 <inline-formula> <tex-math notation="LaTeX">$21\times21$ </tex-math></inline-formula> mm<sup>2</sup>。它基于具有 5 位相位和 9 位增益控制的射频波束成形发射/接收 (TRX) 通道、具有 Wilkinson 分配器/组合器的双嵌套 1:64 分配网络、线路放大器 (LA) 以及具有共享本地振荡器 (LO) 乘法器链的双上/下变频器。差分片上天线馈源通过电磁 (EM) 耦合到高效石英覆盖偶极子天线阵列，该天线阵列在水平和垂直方向上相距 <inline-formula> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula>/2。然后将四个 <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula> 元件相控阵标线在中频 (IF)/LO 域中进行焊线缝合，形成 <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula>-元素相控阵超级十字线，占据<inline-formula> <tex-math notation="LaTeX">$42\times42$ </tex-math></inline-formula> mm<sup>2</sup>。 <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>- 和 <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula> 元素相控阵扫描仰角 ±50° (<inline-formula> <tex-math notation="LaTeX">$E$ </tex-math></inline-formula>-plane) 和方位角 (<inline-formula> <tex-math notation="LaTeX">$H$ </tex-math></inline-formula>-plane) 平面。 <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula> 元素阵列的等效全向辐射功率 (EIRP) 为 37–38 dBm，3 dB 带宽为 60–64 GHz，而 <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula> 元素阵列为 42–44 dBm，每个极化的 3 dB 带宽为 61–63 GHz。使用 <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula> 元素阵列的通信链路通过正交相移键控 (QPSK)、16 正交幅度调制 (QAM) 和 64-QAM 波形进行演示，在 1.3 m 处每个极化的数据速率达到 12–16 Gb/s。据我们所知，本文介绍了第一个完全偏振可扩展的晶圆级相控阵收发器，使用简单的掩模版到掩模版缝合，从而在单个芯片上实现了最先进的功能和复杂性。
This article presents 60-GHz <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>- and <inline-formula> <tex-math notation="LaTeX">$2 \times 256$ </tex-math></inline-formula>-element dual-polarized dual-beam wafer-scale phased-array transceivers with integrated up/downconverters. The <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>-element phased array is built as a single reticle and occupies <inline-formula> <tex-math notation="LaTeX">$21\times21$ </tex-math></inline-formula> mm<sup>2</sup>. It is based on RF beamforming transmit/receive (TRX) channels with 5-bit phase and 9-bit gain control, dual nested 1:64 distribution networks with Wilkinson divider/combiners, line amplifiers (LAs), and dual up/downconverters with a shared local-oscillator (LO) multiplier chain. The differential on-chip antenna feeds are electromagnetically (EM) coupled to a high-efficiency quartz superstrate dipole antenna array placed <inline-formula> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula>/2 apart in the horizontal and vertical directions. Four <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>-element phased-array reticles are then bondwire-stitched in the intermediate-frequency (IF)/LO domain to form a <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula>-element phased-array super-reticle that occupies <inline-formula> <tex-math notation="LaTeX">$42\times42$ </tex-math></inline-formula> mm<sup>2</sup>. The <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>- and <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula>-element phased arrays scan to ±50° in the elevation (<inline-formula> <tex-math notation="LaTeX">$E$ </tex-math></inline-formula>-plane) and azimuth (<inline-formula> <tex-math notation="LaTeX">$H$ </tex-math></inline-formula>-plane) planes. The equivalent isotropically radiated power (EIRP) of the <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>-element array is 37–38 dBm with a 3-dB bandwidth of 60–64 GHz, while that of the <inline-formula> <tex-math notation="LaTeX">$2\times 256$ </tex-math></inline-formula>-element array is 42–44 dBm with a 3-dB bandwidth of 61–63 GHz per polarization. A communication link using the <inline-formula> <tex-math notation="LaTeX">$2\times 64$ </tex-math></inline-formula>-element array is demonstrated with quadrature phase-shift keying (QPSK), 16-quadrature amplitude modulation (QAM), and 64-QAM waveforms, reaching 12–16-Gb/s data rates per polarization at 1.3 m. To the best of our knowledge, this article presents the first fully polarimetric scalable wafer-scale phased-array transceivers using simple reticle-to-reticle stitching, resulting in the state-of-the-art functionality and complexity on a single chip.
