HMC1118 Phase difference between units

Hi,

We are planning to use the HMC1118 switch for a system where we need phase matching between different channels. Each channel will have a HMC1118 switch and we are wondering if you have any data about phase measurement over different units. In case these measurements are not available, do you have any estimation of how could be this phase difference between switches from same lot or different lots?

Thanks and best regards,

Alberto
