Principle of capacitance compensation of power divider based on transmission-line transformer in ultra-shortwave band

A power divider based on transmission-line transformer in ultra-shortwave band is designed. The model of the power divider is given using the telegraph equation. Its characteristics including input SWR, transmission coefficient, isolation and the changes of these characteristics caused by different compensated capacitances are analyzed. The results of calculation indicate that the proper compensation capacitance could decrease the input SWR, increase the transmission coefficient and the isolation. The results of the experiment indicate that the changes of the characteristics of the power divider are consistent with the analysis and calculation when compensated with capacitance.
