| Abstract: | Abstract A broadband CPW phase shifter combining the low loss of high temperature superconductors and the variable dielectric constant of ferroelectrics is described. A phase shift of 80 degrees at 10 GHz with a 30 V bias has been demonstrated. A quasistastic filling factor model has been compared to more sophisticated techniques with excellent agreement. |
