Reactive Power Splitters
Model Dx-19FN series is a collection of low cost two-, three- and four-way wideband reactive power splitters. The new series has been designed to a bandwidth of 700 to 2700 MHz, to include the common cellular, Wi-Fi and WiMAX frequencies, now being incorporated in indoor distributed antenna systems. An added benefit of this series is the guaranteed PIM performance of <-150 dBc when tested with two 20 W test signals. The extremely high reliability required of DAS systems is most easily met with a passive network approach.
