DDC's are used to sample incident and refelcted power without disturbing the charactereistics of a transmission line. Can be used for line monitoring and power measurements usually in the GHz range.

What application did you have in mind regarding high voltage? I doubt this is what you need, but then I do not know the application either.

Wingdings?

Hellow!

are there any dual directional coupler which operate in low frequency(100Mhz-200Mhz),is it possible to make one? thanks!

Well, the 2nd Google hit out of 100's found this one, 100MHz-2GHz range

Unless you are expereinced at high frequency design and layout, I would suggest purchasing one rather than building

Thanks for you searching,i think it is too expensive for us,i found another one:
