1GHz 4-Way Splitter w/Single-Port Power PassingThese splitters allow power passing to a single port, while blocking DC on all other paths, making them perfect for when a splitter needs to be placed between the amplifier and the power supply. They have been designed to meet the highest electrical standards. Careful isolation of the RF and DC paths is required to prevent saturation or burn-out of the ferrite core. This has been accomplished using a separate DC bypass core material which can withstand higher impulse spikes before saturating.
