研究目的
To synthesize group delay time correctors based on contra-directional and trans-directional couplers by obtaining formulas for calculating the frequency characteristics of load resistors to achieve a given frequency dependence of phase and group delay time.

The problem of analysis and synthesis of group delay time correctors based on coupled strip lines with unbalanced coupling is solved. The synthesis method allows for adjusting both group delay time and signal amplitude by specifying frequency-dependent control resistances in directional couplers.
研究不足
The paper does not explicitly discuss limitations; however, it is theoretical and may lack experimental validation. Potential areas for optimization could include practical implementation challenges and sensitivity to parameter variations.
1：Experimental Design and Method Selection:
The methodology involves theoretical analysis and synthesis of group delay time correctors using coupled strip lines with unbalanced electromagnetic coupling. Formulas for transmission coefficients and matrix representations are derived based on specified conditions for directional couplers.
2：Sample Selection and Data Sources:
No specific samples or datasets are mentioned; the work is theoretical, focusing on mathematical models and frequency characteristics.
3：List of Experimental Equipment and Materials:
Not explicitly detailed in the paper; the focus is on theoretical derivations rather than physical experiments.
4：Experimental Procedures and Operational Workflow:
The process includes deriving transmission matrices, solving quadratic equations for equivalent resistances, and synthesizing frequency dependencies based on given group delay time characteristics.
5：Data Analysis Methods:
Analysis involves solving equations for complex coefficients, evaluating roots for physical realizability, and reconstructing frequency responses using mathematical formulas.
