1:1 transformers

I need some precision 1:1 rf transformenrs for PCB mounting. Freq range is 950MHz to 2150 MHz. I know I can buy cheapies such as the M*A/C*O*N E*T*C*1-1-13 but I need better phase matching over the frequency range. Anybody help me out here?

thanks! I've already tried these sources. the problem is that the phase balance of these transformers is very poor at the upper end of their frequency range. It can be as bad as 20 degrees off! I'll keep trying but thanks for your suggestions

Go to www.epcos.com
There are few boradband transformers that may work up to 2500MHz.

if cost is no object

If cost is no object, there are companies that custom make transformers to your specifications. Twenty years ago Lorch was one of them. Some of the microwave magazines have buyers directories which may be useful for you.
