This paper describes a broadband lumped-element power divider composed of multi-section LC-ladder circuits and an isolation resistor. By designing the divider based on multi-section impedance transformer and L-type matching techniques, broadband characteristics of a relative bandwidth of over 100% can be obtained at VHF band. Electromagnetic simulation and experiment for the designed divider have been performed in order to verify the design procedure. The measured results of the fabricated LC-ladder divider at a center frequency of 178MHz utilizing commercial chip elements are good agreement with the simulation results.
