Can the amplitude and phase imbalance of LO signal cause LO feedthrough?

Hello every,

I am wondering whether or not the amplitude and phase imbalance of a LO signal can cause LO feedthrough in a double balanced up-conversion mixer. Can anybody give an answer?

Thanks!

Hi

What is LO amplitude and phase imbalance in this case?

Thanks

I am talking complete switching the transistors.

is this a problem?
