Abstract: An amplification apparatus includes: at least one voltage converter for converting a voltage of supplied power which is supplied from an external power supply source to the amplification apparatus, to a lower voltage; and at least one amplifier unit operable by supplied power which has the lower voltage as converted by the at least one voltage converter, for amplifying a radio frequency signal.

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.

Abstract: In a microwave output device of an embodiment, a part of travelling wave propagating from a microwave generation unit to an output are output from a directional coupler. A first measurement unit generates an analog signal corresponding to a power of the part of the travelling wave by using diode detection, and converts the analog signal into a digital value. One or more correction coefficients associated with a set frequency and a set power of a microwave designated for the microwave output device are selected. The selected one or more correction coefficients are multiplied by the digital value, and thus a measured value is determined.
