Abstract :
A multilayer CPW phase shifter combining high temperature superconductor and ferroelectric thin films produces 150 degrees of phase shift per cm at 10 GHz with a 30 Volt bias at 60 K. A quasistatic model for the effective dielectric constant and loss tangent is presented and compared with data and commercial software.<>
