Typical on wafer Measurements

Bias Conditions :

V5=Vd2,3,4= 5V, Vg1 for Id1= 35mA, Vg = -0.3V, Vc=1.2V

Gain & Noise Figure versus frequency

In jig Measurements

Bias Conditions :

V5=Vd2,3,4= 5V, Vg1= Vg = -0.3V, Vc= 1.2V

All these measurements include the jig losses (about 0.5dB on gain, 0.2dB on noise figure

and 0.3dB on output power).
