A Wilkinson Power Divider with Different Power Ratios at Different Frequencies

The power divider/combiner is very important component for power amplifier design in low power MMIC design and high power system using hybrid scheme. In addition to that, the power divider/combiner is applied for impedance matching, antenna polarization, and phase control in phased array antenna. In this paper, we will consider the power divider/combiner working at two arbitrary frequencies with different power ratios at two output ports including a rigorous analysis and simulation. In order to determine the optimized design parameters, the even-odd mode analysis is carried out rigorously using impedance matching condition and lumped components such as R, L, and C. The validation of analysis and design parameters can be verified using two commercially available softwares based on circuit theory and FIT algorithm, respectively.
