Abstract

In this article, a phase shifter circuit designed for next-generation communication systems was presented. Operating at 4.5–5.5 GHz, the circuit in question is a 3-bit all-pass LC lattice, which was initially analyzed using MATLAB. Following this analysis, the circuit was set up and simulated in advanced design system (ADS) using numerical values derived from the MATLAB simulations. A switch capacitor is employed as the switching element within the circuit. For phase shifts of 45°, 90°, and 180°, the phase errors are 3°, 9°, and 0°, respectively, while the power losses are 1.5 dB, 3 dB, and 1.9 dB, respectively.

4.5-5.5 GHz宽带3位移相器的设计与仿真

本文介绍了一种用于下一代通信系统的移相电路。所讨论的电路工作在4.5-5.5 GHz，是一个3位全通LC晶格，最初使用MATLAB对其进行了分析。在此基础上，利用MATLAB仿真得出的数值，在高级设计系统（ADS）中对电路进行了搭建和仿真。开关电容被用作电路中的开关元件。当相移为45°、90°和180°时，相位误差分别为3°、9°和0°，功率损失分别为1.5 dB、3 dB和1.9 dB。
