Wideband RF transformer

Hello,

I was a bit confused how to construct a wideband transformer for
75ohm <> 50ohm matching. The turns ratio needs to be sqrt(1.5)
as far as I can tell, but I took some photos of a minicircuits part, and
it did not seem to have this, so I'm very curious now how this part is made.

Oh, now I feel embarassed. I checked the data sheet, and I had read the pins wrong. The primary is the orange coil, and the secondary is the orange+green coil (autotransformer). I think there must be five turns of orange, and one turn of green. This would give a ratio (sec/pri) of [5+1]/5,
i.e. 6/5 which is 1.2.

Thanks,

Shabaz.
