Abstract

This letter presents the first on-chip transformer-based six-port balanced-to-unbalanced quadrature hybrid coupler (QHBC). The proposed six-port QHBC employs three transformers to replace eight inductors design in conventional LC-based couplers for miniaturization. Fabricated in CMOS 28 nm, the overall size of the proposed coupler is 0.23 mm $\times0.17$ mm, which is equivalent to $0.046\cdot \lambda _{0} \times 0.034\cdot \lambda _{0}$ , around 20 times smaller compared to the state-of-the-art six-port QHBC. Operating from 48 to 67 GHz, the measured differential and common mode return loss are <−8>−2.2 dB, respectively. The measured output phase and magnitude imbalance are within 10° and 2 dB, respectively. The measured voltage gain varies from −5.8 to −2.8 dB.

基于变压器的 50-67-GHz 六端口平衡至不平衡正交混合耦合器
本文介绍了首个基于片上变压器的六端口平衡-不平衡正交混合耦合器(QHBC)。为了实现小型化,拟议的六端口 QHBC 采用三个变压器取代传统 LC 耦合器中的八个电感器。所提出的耦合器采用28纳米CMOS工艺制造,整体尺寸为0.23毫米/次0.17美元毫米,相当于0.046美元/次0.034美元。\与最先进的六端口 QHBC 相比,体积缩小了约 20 倍。工作频率为 48 至 67 GHz,测得的差模和共模回损分别为 -2.2 dB。测得的输出相位和幅度不平衡分别在 10° 和 2 dB 范围内。测得的电压增益从 -5.8 到 -2.8 dB 不等。
