  • Abstract
    In this paper, a BST coplanar phase shifter with differential phase shift of 98° at 50 V and FoM of 46.7°/dB has been realized. The potential feasibility of integrating BST films into Si substrate as microwave phase shifter and/or coplanar waveguide tunable devices with TiO2 thin film buffer layer has been successfully demonstrated. TiO2 as buffer layer has been successfully grown onto Si substrate by ALD (atomic layer deposition).
