(1) : Typical values are nominal performances at room temperature .
(2) : This inductance can be modified if necessary to tune LNA input capacitance.
(3) The output balance is defined as the S parameters ratio

S
where the port 1 is the input port and
the ports 2 and 3 are the balanced output. The parallel inductance is connected between ports 2 and 3.
Port 1 is loaded on 50
