Abstract

BaxSr1-xTiyMn1-yO3 BSTO thin films have been synthesized using a molecular beam epitaxy system. Novel coplanar waveguide tunable phase shifters have been developed using these Mn-doped perovskite films. The presented phase shifters operate with a phase shift angle of 12 degrees at 10GHz. at an applied bias of 10V on an area smaller than 1mm2, Insertion loss of 3.2 dB is extracted from the S-parameter measurement. Small changes of composition lead to a significant variation of device phase shift, demonstrating the importance of synthesizing suitable structure BSTO film.
