摘要

In this paper, an absorptive balanced-to-balanced power divider is proposed. The new constraint rules at the central frequency are provided for the six-port mixed-mode S-parameters with only four elements being nonzero. Two equivalent three-port networks are deduced for the odd- and even-mode analysis. A microstrip prototype is developed to validate our design. The theoretical, simulated, and measured results all show good mixed-mode performance.
