26 is an odd number when stage combination's used so are used so you may want to consider adding 6 more or taking 2 away and if you're smart enough to figure out how to do this otherwise then you can probably do it your self.
Not when it comes to fet's
Look up MrSuburban, I didn't think I needed to explain that part but the only configuration that you could use 2 transformers would be 2 stages of 13 and I think we all know there aren't any transformers that would stand that much rf voltage.Not when it comes to fet's
Two of these transistors could never drive a stage with 24 or more finals adequately.
There are standard telecom supplies that do this.These transistors also operate on 50 volts so that takes away the ability to use a standard power supply unless you string four in series.
Sure?
The MRF150 have at least 17dB gain on 11m.
On a single device 3w in gives at least 150w out. It means a single MRF150 would be more than adequate to drive 24.
There are standard telecom supplies that do this.
If using a transformer directly from the AC mains, its alot smaller because the current is so much less.
