N2 - In this paper, a miniaturized reconfigurable power divider with frequency selectivity, arbitrary output phase difference and improved isolation is proposed. It is a cascade design of a filtering power divider (FPD) with a miniaturized quadrature coupler (MQC). Both the phase difference (0° or 180°) and the power division ratio of the FPD can be changed as desired, and the output phase difference of the cascaded circuit can be arbitrarily tuned within 360° based on the states of the reflected waves at the outputs of the FPD. Furthermore, a modified isolation network is designed and the isolation between the reflected waves of the cascaded circuit has been significantly improved. The experimental results show that the output phase difference can be continuously tuned from 0° to 360° with the isolation better than 14 dB within the whole frequency tuning range from 1 GHz to 1.3 GHz.
