Does such a converter exist?

Yes; in fact, modern radios often have exactly this kind of power supply
built into them (my Becker transponder is an example of this).

Does your Becker upconvert the voltage to the power output
transistors, or just the control electronics?

I'm sure it controls the voltage to the output stage. Whether it's
upping or downing it probably depends on the input voltage (supply
voltage is given at 9.5-32.2 volts), but I don't know what voltage the
output stage operates at. The rest of the radio might could just use a
voltage regulator off the incoming voltage, but again, just a guess.
