I am building an RF noise bridge (DC-100MHz (200-400, even better) to replace one that failed in my Palomar Engineers antenna tuner. I am using SMD components and have completed the implementation of the noise generator.

Now, I am designing the transformer stage between the generator and the Wheatstone bridge. I was planning on using an FT50-43 ferrite toroid, but I was curious whether any SMD RF transformers could be used. I found that several companies make SMD RF transformers, such as those I've listed below, but I don't know whether they would be good solutions for an RF noise bridge. There is no transmitting involved, so the requirements are simpler.

Assuming the correct taps on the SMD RF transformer, would one be a good substitute for a wrapped ferrite toroid?

Thanks for your comments, Mike
