| Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 84 === We demonstrated for the first time a laser-diode-based
optoelectronic phase-referencing scheme for tracking and
measurement of the amplitude and phase of electro-optically
down-converted RF standing wave patterns in a GaAs microstrip
transmission line up to 16GHz. This technique allows convenient
and accurate on-chip determination of key parameters of the
microwave transmission line such as reflection coefficients and
dispersion characteristis. Taking advantage ofthe excellent
sensitivity for phase measurement of our technique, we analyzed
the phase data of the standing waves of GaAs microstrip
transmission line in the range of 4 to 16GHz and obtained the
dispersion characteristics and reflection coefficients. These
results obtained are in good agreement with theoretical
predictions. We also extend this technique to measure S-
parameter of a transmission.
