We make use of RF Power Amplifiers to amplify the signals we use to run the system.
between 12 and 80MHz bandwidth. Up to 150KWatts for the main cyclotron.
Maybe this page can be expanded somewhat regarding RF amplifiers in this type of environment.
I'm not an expert on the topic...
Maybe this should go under HF?
Transmission amplifiers (probably intended here) which take the RF output of modestly-powered equipment (a few watts) and increase the signal power to a much higher value (hundreds to thousands of watts). The other article on
valve RF amplifiers covers that same ground.
Aside from wattage,
MF–
HF radio amplifiers have very different construction constraints than
VHF–
UHF. (I’m not sure where
LF amplifiers fit.) Only
VLF radio amplifiers are essentially (or actually) identical to audio amplifiers.
So we have different kinds of amplifiers being used all over radio transmission and reception, and the following articles:
But there is no generic
RF amplifier article, the
preamplifier article makes no mention of radio, and the
amplifier article that mentions “radio” roughly three times.
I recommend that all the radio-based articles either be merged or bridged together via a generic
radio frequency amplifier article.
Oppose merger of RF power amplifier and valve RF amplifier. Admittedly, this article has almost no content, but the valve article intends to be a specific type power amplifier. There are exotic and/or historic tube technologies that would not need to be covered in an RF power amplifier article.

I agree, oppose merge. The article currently has images of two amps, neither of which is a valve amp.
Valve RF amplifier is a well focused article and there is no need to mess with it.
Antenna amplifier is not a power amplifier and has different design cirteria, so again, can sensibly be a separate article. It is easy enough to create an overarching
RF amplifier article without messing with any of the existing articles. Those could simply be linked from it. I don't understand why those who want an overarching article have not done that already. This thread has been here for two years without gaining any traction so I am now going to remove the merge templates.

Schematic request
It would be nice to add a schematic to show what a radio frequency power amplifier looks like.
