A miniature microstrip filtering power divider is presented. To effectively reduce the circuit size, the compact folded stub-loaded open-loop resonator is applied to build up the resonator-based power ...

In the above-named article [ibid., vol. 60, no. 9, pp. 2791-2798, Sep. 2012], a balanced-to-balanced power divider/combiner structure is proposed. The proposed structure employs four lumped resistors ...
