ADF4351 balance to unbalance output

I would like to use ADF4351 in my application (1.1 to 1.9 GHz) and I have a question about how to get balance to unbalance output. In page 13 of the datasheet there is a mention of a 1+1:1 transformer. I could not find any suitable transformer with that ratio. The question is about using another

part from Minicircuits (TC4-19+) with 1:4 ratio. Can I use this transformer if I connect a Vcc to the central tap (pin 2) by means a 50 ohms resistor?

can you make any suggestion about any other transformer?.

Many thanks.
