Steve, This won't be a solar power application. They want to get the power draw down to around 3-4 amps to reduce the size of the power supply needed. Rather than have a big Astron sized unit, they want to use a smaller switching supply. In addition, the RF output only needs to be a few watts so pumping 25-40W out isn't necessary.
