RT Journal Article T1 Note: Tunable notch filter based on liquid crystal technology for microwave applications A1 Urruchi del Pozo, Virginia A1 Torrecilla Rosell, Javier A1 Sánchez-Pena, José Manuel A1 Garbat, K. A1 Marcos Lucas, Carlos AB In this work, a compact design of an electrically tunable notch filter, based on liquid crystal (LC) technology, has been designed, manufactured, and characterized. The proposal has been achieved through particular configuration schemes with low cost inverted-microstrip structures and conventional spurlines structures due to its ease of integration. Central frequency tunability has been induced by applying low ac voltages, thus involving low power consumption. For these devices, filter responses have been approached specifically at microwave C-band frequency allocated for many satellite communications applications. Also, it has taken advantage of new highly anisotropic nematic LC mixtures at those frequency ranges.
