Computational-Efficient Signal Processing Solution to Frequency Quadrupler Based High-Frequency Vector Signal Generator

Due to advancements in technological trends, interest in frequency multipliers is increasing in the research community. However, the linearization approach on frequency multipliers differs from that of power amplifiers and hence cannot be directly implementable for end-to-end high-frequency systems. This paper discusses recent computational approaches and proposes a model for improving performance metrics, especially the adjacent channel power ratio. This paper shows theoretical trends, mathematical approaches to current trends, and the proposed model. It then establishes the theory by experimental implementation and compares the proposition results to the models in the literature.
