In this paper, a wideband filtering power divider is designed by employing a stub-loaded ring resonator. The first two resonant modes of the ring resonator are excited to form the filtering passband. To improve the passband skirt, two transmission zeros near the passband are then introduced by mounting an open stub along the ring resonator. After installing two coupled lines at two output ports, one...
In this paper, a synthesis of filtering power dividers with frequency invariant complex source and load impedances is presented. Based on the coupling resonance theory, the synthesized power divider can achieve a bandpass filtering response with sharp roll-off skirts and in-band equi-ripple level. Under the definition of power wave, the coupling matrix for the power divider based on the coupled-resonator...
In this paper, authors present some research results of traveling-wave waveguide-banded spatial power divider/combiner. First, after theoretical analyzing, authors expand the bandwidth of traveling-wave waveguide-based power divider/combiner based on typical planar compatible structure, and then constructed symmetric coupling structure with the reduced height waveguides to doubles the combining pathways...
