a query related to mixer

hello
i m designing a 4 port mixer. i m givind 10mv RF (ac signal). can any1 tell what amplitude of ac signal i should at LO port.

The LO level in a mixer depends by the type of the mixer. Single stage additive (passive or active), single balanced (passive or active), double balanced (passive or active), etc.

i m designing active double balanced mixer.

If is a Gilbert type mixer the LO level should be about 0dBm.
