Abstract: This disclosure is directed to a power combiner/divider with improved operating frequency range (e.g., bandwidth) compared to other power combiners/dividers. The power combiner/divider may include an isolation circuit including a first resonant circuit and a second resonant circuit coupled to terminals (e.g., input terminals, output terminals) of the power combiner/divider. The first resonant circuit may attenuate signals having frequencies in a first frequency range below an attenuation threshold between the terminals of the power combiner/divider. The second resonant circuit may attenuate signals having frequencies in a second frequency range below an attenuation threshold between the terminals of the power combiner/divider. Accordingly, the isolation circuit may improve isolation between multiple terminals of the power combiner/divider at a wider bandwidth compared to other power combiners/dividers based attenuating cross-talk between the terminal at the first frequency range and the second frequency range.
