rf transformator and impedance differetiation and phase difference

Hello everyone

I will use minicircuit TCM1-63AX+ rf transformator for differential rf port of mixer IC. My question is this rf transformator only differetiate impedance of mixer RF+ and RF- port or differentiate impedance and give phase difference between two signals.

It's a 1:1 Balun Transformer that is used to convert Balanced-to-Unbalanced ( or vice versa) inputs/outputs.It has no effect on impedances.
But amplitude and phase unbalance specs. are very poor due to its' wideband characteristics.Irecommend you to use a narrowband one which is more convenient at the frequency where you would at.
Because if you use it for a single frequency or for a narrowband, you may not obtain desired specs. for instance power for PAs, Sideband rejection for I/Q Modulators etc.
If I'd were you , I select more proper one with narrowband.

thanks bigboss I will consider your recommendation and tips
