Abstract

A microfluidically reconfigurable slow wave phase shifter (MRPS) with integrated actuation is introduced. MRPS is based on a selectively metalized plate (SMP) repositionable within a microfluidic channel placed in close proximity to a microstrip line. SMP repositioning creates a variable capacitive loading to alter the speed of the propagating wave. The device exhibits < 2 dB insertion loss (IL) and a reconfiguration time of 50 ms. The

, and phase performances are characterized to be stable with respect to gravity by no more than 0.16 dB, 3.02 dB, and 7.73° variations, respectively. Vibration test shows 0.08 dB in IL, 1.72 dB in return loss (RL), and 4.23° in phase variations. The device is expected to handle 5.2 W of continuous RF power.

集成驱动的微流体可重构毫米波慢波移相器

介绍了一种集成驱动的微流体可重构慢波移相器。MRPS基于可在微流体通道内重新定位的选择性金属化板（SMP），该微流体通道放置在微带线附近。SMP重新定位产生可变电容负载以改变传播波的速度。该器件表现出<2dB的插入损耗（IL）和50ms的重新配置时间。$|S_{21}|$、$|S_｛11}|$和相位性能相对于重力分别稳定不超过0.16dB、3.02dB和7.73°的变化。振动测试显示IL为0.08 dB，回波损耗（RL）为1.72 dB，相位变化为4.23°。该设备预计可处理5.2W的连续射频功率。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
