ABSTRACT:
A passive impedance matching device incorporates a pair of power splitters, each having a transformer core with a center tapped winding shunted by a resistance having a predetermined value. The power splitter windings have their center taps connected to the input terminals. The arrangement creates a virtual ground and thus avoids the need to create an unbalanced signal. By cascading stages the input signal can be split any number of times. Unused outputs are terminated with their characteristic impedance.
