Experimental Study of UHF/SHF Dual-Band Semi-Lumped-Element Power Dividers

In this paper, simple lumped-element power dividers with 9 elements that can be matched at arbitrary two frequencies are described. About those circuits, assuming that the ratio of two frequencies is 4, we design and analyze the dividers that operate in the UHF/SHF bands used in IoT and 5G (sub6 band). The effectiveness of the proposed dividers has been confirmed by fabricating and measuring a prototype circuit.
