Abstract

A DC-to-40 GHz traveling wave active power splitter has been designed to provide a high dynamic gain variation from -2 dB to 12 dB with 0.5 dB 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 50 Ohms load. Our broadband active power splitter is suitable in the most multiple division receivers to fashion the logarithmic output power.
