Notes:

1. The Fmin values are based on noise figure measurements at multiple input impedances using Focus source pull test system. From these

measurements a true Fmin is calculated.

2. Scattering and noise parameters are measured on coplanar waveguide made on 0.010 inch thick ROGER 4350. The input reference plane is at the

end of the RFinput pin and the output reference plane is at the end of the RFoutput pin as shown in Figure 7.

3. Idd can be obtained by varying the Vg1/Vg2. Refer to figure 7.
