    Please some one help me understand how this circuit operates. My knowledge is very thin.

    1) Why does this LNA have two sources of power? Pin 1 and Pin 5?

    2) What is the 1 K resistor doing?

    3) what is the 10 nH inductor doing?

    4) what is the 5.6nH inductor doing?

    5) the 1k and the 10nH are in parallel correct?

    6) Could I combine the 10 nH and 5.6 nH to get a equivalent inductor circuit. If so would it go in series or parallel with the resistor.
