The embodiment of the invention provides a detection jig and a detection device for a liquid crystal phase shifter. The detection jig for the liquid crystal phase shifter comprises a first jig plate and a second jig plate, the first jig plate and the second jig plate are detachably connected, and the first jig plate and the second jig plate are oppositely combined to form a containing cavity used for limiting the liquid crystal phase shifter; a first waveguide adapter, one end of the first waveguide adapter is used for being electrically connected with a test signal output end of the vector network analyzer, the other end of the first waveguide adapter is connected with the first jig plate, and the first waveguide adapter is used for being coupled with a first signal end of the liquid crystal phase shifter in the accommodating cavity; a second waveguide adapter, one end of the second waveguide adapter is connected with the second jig plate and is used for being coupled with a second signal end of the liquid crystal phase shifter in the accommodating cavity, and the other end of the second waveguide adapter is used for being electrically connected with a feedback signal input end of the vector network analyzer. According to the embodiment of the invention, the direct detection of the liquid crystal phase shifter is realized, the tedious degree of the detection process is effectively reduced, the detection efficiency is improved, and the detection precision of the liquid crystal phase shifter is also improved.
Description
technical field [0001] The present application relates to the technical field of detection of liquid crystal phase shifters. Specifically, the present application relates to a detection fixture and detection device of liquid crystal phase shifters. Background technique [0002] Liquid crystal phase shifter is a programmable optical phased array using liquid crystal as electro-optic material. Applying a DC bias voltage to the electrodes of the liquid crystal phase shifter will generate a DC steady-state electric field distribution in the liquid crystal cell of the liquid crystal phase shifter. Microscopically, the liquid crystal molecules in the liquid crystal cell will be subjected to electric field force, and the axis orientation will be deflected; macroscopically, the The relative dielectric constant of the liquid crystal layer is changed. When the microwave passes through the liquid crystal phase shifter, the change of the relative dielectric constant of the liquid crysta...
