MGA-631P8 Scattering Parameter and Noise Parameter Test Setup
Figure 35. Test Setup for S & Noise Parameters data, C3=5.6pF (Rohm MCH155A5R6CK)
Typical Noise Parameter, Vd=4V, Id=60mA, applicable to any R1 due to high reverse isolation
Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based
2. S and noise parameters are measured on PCB. The PCB material is 10 mils Roger RO4350. Figure 35 shows the input and output reference plane.

on a set of 16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements a true Fmin
is calculated.
