摘要

本文介绍了基于MACOM变容二极管负载的CPW线的分布式移相器的理论研究和实验表征。给出了电路仿真与电磁仿真相结合的方法，并与实测结果进行了比较。在这项工作中，我们还提出了一种阻抗匹配方法，可以在不增加电路的情况下调整移相器。通过所提出的移相电路的全局ABCD矩阵得到了移相的表达式，并与实测结果进行了比较。在Matlab和ADS (Momentum)软件上进行了仿真，并将仿真结果与实际制作的移相器进行了对比，验证了理论建模和实验表征，得到了较好的一致性。

Theoretical and experimental characterization of distributed analog phase shifter

This paper describes a theoretical study and experimental characterization of distributed phase shifter based on CPW line loaded by MACOM varactor diode. A circuit simulation combined with electro-magnetic simulation is presented and compared with measurement. In this work, we present also an impedance matching method allows adapting our phase shifter without additional circuit. The expression of phase shifting is obtained through the global ABCD matrix of proposed phase shifter circuit and compared with the measurement. The simulations are carried out on Matlab and ADS (Momentum) software's, a comparison between two simulations and measurement of fabricated phase shifter is made in order to validate the theoretical modeling and experimental characterization, good agreement is obtained.
