Abstract
The present invention relates to switchable components for high-frequency technology, in particular microwave technology, which use liquid-crystalline dielectrics, to the liquid-crystal materials, to the use thereof, and to a process for the production of the components, for their operation and for improving their characteristics.
Claims23
A controllable component for a high-frequency application comprising, as controllable medium, a liquid-crystal material whose phase shifter quality and/or whose material quality is 10% or more greater than that of an otherwise identical component containing pentylcyanobiphenyl instead of said liquid-crystal material.
A controllable component for a high-frequency application according to claim I comprising, as a controllable medium, a liquid-crystal material whose phase shifter quality is 15°/dB or more and/or whose material quality is 3.5 or more.
