Re: WDG025 13cm pre-amp datasheet?

Hi Graham
I built his 13cm converter for Oscar 40, and I think all Charlie’s modules were designed for 12V.  Presumably the preamp has a voltage regulator in it , so add about 3v to the voltage of the regulator and that will give you the minimum, supply voltage. Most regulators work up to about 30v input, but you have to derate their current to avoid overheating. Google the data sheet and it will tell you.
Hope this helps.

Does anyone have some information on this pre-amp? I'm wondering what voltage supply it will function with. I might need to reduce from 24V?
