摘要：本文提出了一种用于120 GHz相控阵收发器的d波段移相器，实现在120 nm SiGe bi - m操作系统进程$(\mathbf{f}_{\mathbf{T}}/\mathbf{f}_{\mathbf{max}}=\mathbf{260}/\mathbf{340\ GHz})$上。所提出的移相器采用两级反射型拓扑进行0-180°操作，之前是基于balun的逆变器，以获得完整的360°相移，分辨率为11.25°。移相器具有均匀的插入损耗特性，在所有相态上的插入损耗变化小于1db。在122 GHz处测得的IL为$\mathbf{5.8}\pm \mathbf{0.3\ dB}$。测得的122 ~ 123 GHz的均方根增益和相位误差分别为$< \mathbf{0.2}\ \mathbf{dB}$和$< \mathbf{3}^{\mathbf{0}}$。该IC占用$\mathbf{750\ x\ 540}\ \pmb{\mu} \mathbf{m}^{2}$的面积，功耗为30m W。
Ahstract- This paper presents a D-Band phase shifter for 120 GHz phased array transceivers, implemented in 120 nm SiGe BiC-M OS process $(\mathbf{f}_{\mathbf{T}}/\mathbf{f}_{\mathbf{max}}=\mathbf{260}/\mathbf{340\ GHz})$. The proposed phase shifter employs two stages of reflection-type topology for 0–180° operation, preceded by a Balun-based phase inverter to obtain a full 360° phase shift with 11.25° resolution. The phase shifter exhibits uniform insertion-loss characteristic with less than 1 dB insertion loss variation over all phase states. The measured IL at 122 GHz is $\mathbf{5.8}\pm \mathbf{0.3\ dB}$. Measured RMS gain and phase error at 122–123 GHz are $< \mathbf{0.2}\ \mathbf{dB}$ and $< \mathbf{3}^{\mathbf{0}}$, respectively. The IC occupies area of $\mathbf{750\ x\ 540}\ \pmb{\mu} \mathbf{m}^{2}$ and consumes 30 m W.
