So what is the voltage out the finals on a solid state transmitter?


There are no finals. Just a bunch of combined modules. The Nautel 50 has 8
RF and 4 modulator power modules. There is no final stage.

Ain't power MOSfet's a wunnerful thing?

Ok, Don't call the modules "finals" then but what is the output voltage
to the antenna? I would like to know what the RF current is as the
output is supposed to be 50KW.

You know the skin effect will concentrate all the current into the
conductor skin. I wanted to calculate the current density.

I wonder what the power loss is in the hardline from transmitter to
antenna?

I expect the parallel solid state design will have much lower voltage
and higher current than older tube designs. It would then follow that
transmitter destruction is more likely to result from connector problems
in a solid state transmitter where the higher voltage tube designs would
result from insulator breakdown or flashover.

Almost all phasors or lines are50 or 52 ohms today.

The line manufacturers all have specs on loss as a function of frequency.

It all ends with a match to 50 ohm line at the output fitting on top of the
box.
