AD8317 in a differential input configuration

Hi!

 

The AD8317 log detector has a fully differential design, but the datasheet only describes a single ended input configuration. I would like to have a differential input configuration (a balun at the AD8317 input) to increase the dynamic range. I'll use it at 8GHz. Any recommendations, comments, differential measurements/plots/graphs? Would a differential input make a difference at all? Many thanks!
