标题： A High-Resolution Transmission-Type (TT) Phaser Based on Reflection-Type (RT) Units for Radio Analog Signal Processing (R-ASP)

摘要： 一种基于反射型（RT）移相器单元的高射频模拟信号处理（R-ASP）分辨率的传输型（TT）移相器被引入，进行了理论研究和实验演示。首次表明，由于其群延迟摆幅与谐振器耦合机制（导纳变换器）相关的反射系数成正比，容易最大化为1，而不是与耦合线耦合系数成正比，通常受限于小于1的值，如在RT情况下。此外，详细的灵敏度分析显示，所提出的移相器同时具有高R-ASP分辨率和对制造公差的低灵敏度，这使其成为R-ASP的理想解决方案。所提出的移相器在约4 GHz的分数带宽约为50%的范围内表现出5 ns的群延迟摆幅。 显示英文摘要

摘要： A high Radio Analog Signal Processing (R-ASP) resolution transmission-type (TT) phaser based on reflection-type (RT) phaser units is introduced, theoretically studied and experimentally demonstrated. It is first shown that RT phasers inherently exhibit higher R-ASP resolution than their TT counterparts because their group delay swing is proportional to the reflection coefficient associated with a resonator coupling mechanism (admittance inverter), easy to maximize towards unity, rather than to a coupled-line coupling coefficient, typically restricted to values will inferior to unity, as in the RT case. Moreover, a detailed sensitivity analysis reveals that the proposed phaser is simultaneously features high R-ASP resolution and low sensitivity to fabrication tolerance, which makes it an ideal solution for R-ASP. The proposed phaser exhibits a 5 ns group delay swing over a fractional bandwidth of about 50% around 4 GHz.
