  • Amplification apparatus
    Patent number: 10714407
    Abstract: An amplification apparatus includes: a signal splitter for splitting an input radio frequency signal and outputting the resulting split radio frequency signals; a plurality of amplifier units for amplifying the radio frequency signals outputted from the signal splitter, the amplifier units being disposed circularly to form a generally cylindrical shape; a plurality of water cooling heat sinks disposed circularly at positions corresponding to the positions of the plurality of amplifier units so as to cool the plurality of amplifier units by cooling water; and a signal combiner for combining the radio frequency signals outputted from the plurality of amplifier units, respectively, and outputting the resulting combined radio frequency signal.
