Abstract

In this paper, we present a new filtering power divider structure that has a reflectionless response at the two output ports and excellent isolation performance between the two output ports. Hence, the presented filtering power divider can be employed in, for example, combining two signals in two paths without producing signals reflected back to both paths. For obtaining the aforementioned new features of the presented filtering power divider, we have developed a new isolation network made with a resonator, two resistors, and two inverters. We provide analytic design equations so that time-consuming optimization or parametric study is not required in designing filtering power dividers. For verifying the new divider structure and the design equations, we have designed, fabricated, and measured a second-order microstrip reflectionless filtering power divider.
