thanks for your answer but I need to know exactly if the wilkinson power divider is better then Coupler with comparing in insertion loss and return loss and which one has smaller size if it adds to Doherty amp.?

Wilkinson power divider is obviously a good option for using if your bandwidth is not very much. However you can use it for higher bandwidths with a little degradation in quality. Also its size is smaller than any other power divider.
