How to drive this Buck converter?

[audioguru]

A class-C RF amplifier driving an LC tuned cuircuit is about as efficient as an RF amplifier gets.

The very low power AM broadcast band transmitter uses a linear oscillator and does not have an RF amplifier.

Maybe there is confusion with my post,

I did't say exactly I m using a buck converter as an RF amp, I just want to design a buck converter which is part of the voltage supply system of the RF amp.

But this buck and a linear stage will feed the RF amp according to the envelope (10-40 MHz) of the input RF signal and then the supply voltage moves with the input RF signal...
