No, you can't get unique tech in any other way than finding it yourself. It cannot be traded or analysed.
Note that normal tech (as in non-racial and non-ruin tech) can be obtained be analyzing even if you don't have the tech requirement to research it. Example: if you don't have Chemistry, you can still analyze ships to get armor.

PS (edit): yes, actually what SJ said is technically more correct. They can be traded, but won't be understood. So in practice they can't be traded
