文摘

A novel ultra-wideband (UWB) power divider with bandpass-filtering frequency response has been presented. The shorted-end coupled lines and the open/short-circuit slotlines are introduced to this presented power divider. An isolation resistor R is located across the slotline for improving the isolation between the output ports of the power divider. Based on even and odd mode analysis, an analytical model of the presented power divider structure has also been proposed. An UWB power divider with passband response has been designed, fabricated, and measured. The measured results verify the predicted attractive features. It can be seen that the presented UWB power divider can not only divide/combine the power of microwave signals, but also reject unwanted frequency signals to better regulate the UWB performance.
