Apply Vg before Vd. Equivalent wire bonding : 0.15 nH Equivalent wire bonding : 0.15 nH The CHA3023 could be used without Vg2 bias. There is a resistor bridge inside the chip. This one generates the correct value of Vg2 Bias. Pads G2a and G2 must be connected. Equivalent RF Wire Bondings: 0.15 nH (typical length of 200µm for a 25µm diameter wire).
