For 50 watts, we use two Japanese power modules and Wilkinson power dividers for splitting and combining. We build an IPA that supplies the required drive for the two modules, it's a one transistor buffer that puts out about 1 watt but it's output is variable from 1/2 watt to 1 watt. This drives the two modules in parallel and the output is combined with another Wilkinson. I think Scott has pictures - it was never "officially" written up that I'm aware of. Kevin
