Power amplification device and television signal transmission system
Abstract:
A power amplification device comprises an amplifying unit and a combining unit. The amplifying unit is provided with a plurality of groups of amplifier circuits that amplifies the power of a radio frequency signal. The plurality of groups of amplifier circuits each includes a predetermined number of the amplifier circuits. The combining unit includes a plurality of combiners. The amplifying unit is housed by a first housing and the combining unit is housed by a second housing which is separate from the first housing. The amplifying unit is configured to be attachable to and detachable from the combining unit. The amplifying unit is configurable by one or more control voltages to perform amplification in classes AB, B and/or C. The amplification in classes AB, B, and/or C is compatible with a type of the combiner.
