A DC-to-40GHz traveling wave active power splitter has been designed to provide a high dynamic gain variation from -2dB to 12dB with O.5dB gain flatness over the entire frequency band. The active power splitter can also operate as a conventional Traveling wave Low noise amplifier having a good NF when one of the arms is in the off-state condition or terminated by 500hms load. Our broadband active power splitter is suitable in the most multiple division receivers to fashion the logarithmic output power.978-1-4244-1780-3/08/$25.00
