Notes :
(1)
Typical values are nominal performances at room temperature
(2)
This inductance can be modify if necessary to tune LNA input capacitance
(3)
The amplitude variation is defined as the maximum level – minimum level over the given bandwidth
(4)
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
