LNA Differential impedance matching

    I'm designing a differential CMOS LNA and its output needs to match to
    100 Ohms DIFFERENTIAL. What does this differential mean? Does it mean
    that I take each transistor output impedance and match it to 50 Ohms or
    it involves something entirely different??

    Assuming this is how I match, only for simulation purposes if I use an
    ideal balun to convert diff. to single-ended would I terminate the
    single ended side at 50 Ohms or 100 Ohms? What I'm asking is the port2
    terminal would have 50 or 100 Ohm reference impedance?? Someone please
    answer...thanx
