A Novel Microwave Tunable Band-Pass Filter Integrated Power Divider Based on Liquid Crystal

Abstract EN

This paper proposes a novel microwave continuous adjustable band-pass filter integrated power divider based on nematic liquid crystals (LCs).

The proposed power divider uses liquid crystal (LC) as the dielectric material.

It can realize phase shift by changing the dielectric anisotropy, when biasing the high anisotropy nematic liquid crystal.

It is mainly used in microwave frequencies.

It has a large number of advantages compared to conventional filter integrated power divider, such as low loss, multifunction integration, continuous adjustable, miniaturization, low processing costs, low operating voltage, high phase shift, and convenient manufacture.

Therefore, it has shown great potential for application.
