| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 108 === In this thesis, a vector modulator (EVAL-HMC631LP3) is employed to determine some essential parameters including phase and ampli-tude-imbalance. Here, such a vector modulator is utilized as a 360 degree phase shifter; that is, the input sine signal will have a phase delay by giving DC I (in-phase) and Q (quadrature phase) voltage, respectively. The mathematical procedure for extracting the circuit parameters was devel-oped. Additionally, one measured a large amount of input-output relation of the vector modulator using a vector network analyzer. Significantly, the deep learning method based on artificial neural network architecture was conducted to obtain the predictive model successfully.
