Schematic of the phase shifter.
Transmission characteristics in the small-amplitude regime without application of control current. (a) Modulus of the transmission coefficient measured in the continuous-wave and pulsed regimes, as indicated, (b) phase of the transmission coefficient. Points—experiment and line— best linear fit of the experimental data in the range of small frequencies.
(a) Phase shift as a function of the control current transmitted through the wire conductor for two different values of the peak power of microwave pulses applied to the input of the phase shifter, as indicated. (b) Dependence of the modulus of the microwave transmission coefficient on the current for and 300 mW. The data are normalized at .
Slope of the phase-versus-power characteristic as a function of the control current.
