Abstract
We report on the performance of a Ku-band gold/ Ba0.5Sr0.5TiO3/LnAlO(3) (Au /BSTO/LAO) coupled microstip line phase shifter fabricated with a 370 nm th ick BSTO film. Two hundred degrees of contiguous relative insertion phase s hift (Delta phi(S21)) with insertion losses of 4.6 dB, were measured at roo m temperature, 14.3 GHz, and maximum de voltage of 400 V. These results rep resent significant progress toward viable compact, low-loss, thin-film ferr oelectric-based phase shifters nr room temperature. (C) 1999 John Whey & So ns, Inc.
