An Overlooked Class of N-way Power Dividers Combining Resistive and Reactive Dividers

An overlooked class of in-phase, equal power split, N-way power dividers combines resistive and reactive dividers. This "partial resistive divider"(PRD) has a series input transformer similar to reactive dividers and series resistors at the output port...
Figure 1 Families of equal power dividers. The "partial resistive divider" (PRD) is often overlooked when selecting a power divider circuit. This article compares its attributes with those of resistive, reactive and Wilkinson divider circuits. Figure 1 shows the basic resistive, reactive, partial resistive divider (PRD) and Wilkinson divider...
