Abstract

In this paper, a new configuration embedded with two filters and one resistor is proposed, which has the dual function of power splitting and filtering. The filter is based on stepped impedance ring resonator. All the even- and odd-mode resonant frequencies and transmission zeroes of the stepped impedance ring resonator are derived based on the even- and odd-mode analysis. Three interdigital-coupled lines are applied at the input port and output ports to achieve a bandpass response and suppress the second harmonic. For verification, a sample operating at the central frequency of 2 GHz is fabricated and tested. The measured results show the power divider has good performance on impedance matching, frequency selectivity, and isolation over the operating band.
