Where can I find good information about the principle and the design of
linear power amplifier using semiconductors, up to the full legal
power limit ?
Is it only possible to use power splitter ? I have seen broadcast
transmitters in the power range of many hundred of kW's, having an
power efficiency of more than 90 %. Do they use power splitter or
another design ?
The biggies for AM are often essentially huge D-to-A converters.
The FM ones use splitters and combiners.
Neither are linear amplifiers.
