Hello!

Is it necessary to have equal or the same gain in positive and negative output of differential amplifier?

Thanks :)

If you have biased symmetrically and correctly, in-spite I should say, If it is biased symmetrically, you will get equal gain.
This is ac gain and there is no +/- sign for AC input signal.
