报道了一种基于MEMS驱动手指调谐的单极带通滤波器的W波段连续可变传输型移相器。调谐是通过两个半波长的长导电指以反平行的方式同步向上旋转来实现的。指形偏转导致分布的可变并联电容，这进而导致可变模拟相移。在0~26V的直流偏置电压范围内，在106 GHz频率下，传输相位可连续变化至46.4°，插入损耗小于3.4d B。©2012 Wiley期刊，Inc.微波OPT Technol Lett 54：465-468,2013；在线查看本文，网址为wileyonlinelibrary.com。DOI 10.1002/MOP.27390
A continuously variable transmission type W‐band phase shifter based on a single pole bandpass filter tuned by MEMS actuated fingers is reported. Tuning is achieved by means of two half‐wavelength long conductive fingers that synchronously rotate upwards in an antiparallel fashion. The fingers deflection results in a distributed variable shunt capacitance which in turn leads to a variable analog phase shift. For an applied DC bias voltage between 0 and 26 V, the transmission phase can be continuously varied up to 46.4° at a frequency of 106 GHz with an insertion loss of less than 3.4 dB. © 2012 Wiley Periodicals, Inc.
