分析了单片数字移相器的移相原理，介绍了各基本移相状态的设计方法和结构，并设计了一个34-36 GHz的5位数字移相器。基于GaAs PHEMT工艺，我们使用ADS Momentum微波设计环境进行仿真。最后，研制的5位数字移相器的主要指标为：主移相态的均方根值小于2.3 °，回波损耗小于-14dB，插入损耗在8.0 ~ 9.1dB范围内，插入损耗波动在-0.6 ~0.4dB范围内，芯片尺寸为3.0mm × 2.0mm;控制电压为- 5 v / 0 v。试验结果表明该设计方法是可行的，并指出了各种型号的设计需要改进的地方。
This article analyzes the phase shift principle of the monolithic digital phase shifter, and introduces the design method and the structure of each basic shift phase state, and design a 34-36 GHz 5-bit digital phase shifter. Based on the GaAs PHEMT technology, we used ADS Momentum microwave design environment to perform simulations. Finally, the main index of the 5 bit digital phase shifter are: the RMS values of the main shift phase state is less than 2.3 °; Return loss is less than - 14 dB; Insertion loss is within the range of 8.0 ~ 9.1 dB; Insertion loss fluctuations is within the range of - 0.6 ~ 0.4 dB; The chip size is 3.0 mm × 2.0 mm; Control voltage is - 5 v / 0 v. the test result shows that this design method is feasible, and points out that the design needs to be improved in various of models.
