We propose a Wilkinson power divider that suppresses harmonics using radial open stubs. By combining quarter-wavelength coupled lines and radial open stubs, broadband harmonic suppression can be realized. Simulation of the proposed configuration s...

This paper presents broadband 4-way power divider with 45° phase differences between output ports. The divider is developed by combining a broadband 45° power divider and 90° power dividers, and is implemented on a 4-layer FR4 substrates, by using...

This letter presents miniaturized Gysel power dividers using lumped-element components. The characteristic impedances of all the equivalent transmission lines in these dividers are fixed to the same values based on even and odd mode analysis, thus...
