As has been mentioned by many already, the difficulty is getting the heat OUT of that miniscule device. Loads require good thermal conductivity, and a lot of surface area to dissipate the heat, and if the vendor has any applications/design info for actually making a working load, that would be the place to start.

Here, is what the size of an 800 Watt conventional, Carbon element, oil bath, continuous duty rated, load looks like. I guess your load is not much bigger than the size of the "N" connector on the end of this load. You have some serious thermal transfer problems to overcome, especially if you want to achieve an 800 Watt continuous dissipation rating. By no means am I trying to discourage you from going for the gold here, just trying to give you a sense of scale.
