Hi If your intention is to run a mixer with saturated inputs …. just run an X-OR gate. It will handle the high level signals much better than an over-driven analog part.

If you look at the schematic of an XOR gate IC and compare it to the schematic of, for example, an MC1496 mixer, you will see a lot of similarity. If the gate is of the ECL type, it will have the addition of emitter followers, but that it a minor detail of implementation. I'm not sure there is a huge difference. ECL is a great logic family in general (self-confessed ECL-phile here :-) but it is probably the worst for phase noise, compared to the saturating logic types.
