In this work, tunable series and parallel resonators based on a nematic liquid crystal cell as variable capacitance are proposed and characterized. Tunable resonance frequencies in the range of kHz have been obtained for the combination of the inductance and the liquid crystal cell (capacitance) used in the proposed circuits. Tuning range in frequency obtained is around an octave.
在这项工作中,提出并表征了基于向列型液晶盒作为可变电容的可调串联和并联谐振器。在所提出的电路中,利用电感和液晶盒(电容)的组合,已获得了kHz范围内的可调谐振频率。所获得的频率调谐范围约为一个倍频程。
