Abstract

Ferroelectric/superconductor thin films(Ba0.05Sr0.95TiOJ3YBa2Cu307-a)are used to realize an electrically tunable, low-loss composite right/left-handed transmission line. A resistive line is implemented as both DC bias path and RF choke. The whole device maintains an all-planar configuration. The composite right/left-handed transmission lines are well matched showing a wide pass band. As a phase shifter, the figure-of-merit of the device is evaluated and compared with that of a room-temperature
device based on Bao.5Sro5TiO3 and silver. The effect of wire bonding on the performance is discussed.
