[Amps] need a channel 11 VHF high band TX? tspa

[John T. M. Lyles]

I am developing an RF amplifier system for the particle factory, with 
a nice new tetrode. However, I need a new driver, as I am replacing 
the original two tube system with a single tube driven by silicon- 
based technology. However, getting that stage hasn't been so easy. It 
operates on 201 MHz, close enough to VHF high band TV that I could 
use a transmitter, stripped of all the HDTV hardware (or NTSC for 
that matter). I need 25 kW of peak output, from a pulsed AB1 linear 
amplier. Its right at the point where MRF151G, MRF174, etc start to 
crap out of gain/power/bandwidth. Its a BIG transistorized amplifier 
for me, otherwise would love to build it. What a project. We plan to 
visit NAB this month in Vegas  and kick the tires on a couple of 
major brands.
