A novel balanced-to-unbalanced (BTU) all-port reflectionless filtering power divider without loading additional absorptive branches at input and output ports is proposed in this paper.The proposed power divider includes two reflectionless filtering networks, four transmission lines, a phase inverter, and two isolation resistors.Unlike the existing filtering power dividers that require additional absorptive branches to be loaded at each port to achieve reflectionlessness at all ports, the proposed power divider ach…
