- 論文の詳細を見る
This paper proposes a new phase shifter based on a conductor-backed coplanar waveguide structure loaded periodically with reversed bias varactor diodes. Driving the phase shifter with serrodyne(sawtooth)modulation results in frequency shifting with a good sinusoidal waveform. Using this phase shifter with coherent technique yields a high accuracy and reliable microwave reflectometer. The experimental results of measured reflection coefficients for 25 and 50 Ω loads using this reflectometer system agree very well with ones from a current commercial network analyzer.
