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 |S21||S_{21}| , |S11||S_{11}| , 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.

具有集成驱动功能的微流体可重构毫米波慢波移相器


介绍了一种具有集成驱动功能的微流体可重构慢波移相器（MRPS）。 MRPS 基于可在紧邻微带线的微流体通道内重新定位的选择性金属化板 (SMP)。 SMP 重新定位会产生可变电容负载，以改变传播波的速度。该器件的插入损耗 (IL) < 2 dB，重新配置时间为 50 ms。 |S21||S_{21}| , |S11||S_{11}| ，相位性能相对于重力稳定，变化分别不超过 0.16 dB、3.02 dB 和 7.73°。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°。该器件预计可处理 5.2 W 的连续射频功率。
