HMC631 Matching

Hello,

I have three questions about the HMC631 vector modulator...

1- Is there a S-parameters file describing the behavior of the component de-embedded or on the eval board ?
2- Does the input (or output) impedance change with the voltages applied on the IQ inputs ?
3- In order to guarantee the phase/amplitude modulation performances, is it recommanded to add a matching circuit at RF input/ouput ports or is it better for the HMC631 to be connected directly to a 50 ohms source/load ?

Thanks.
