Typical Noise Parameters
(VDS = 2 V, IDS = 15 mA)
Freq.
Both noise and S-parameters include bond wires. Two gate
bond wires and two drain wires are each approximately
325 µm (13 mil) long. Four source bond wires (2 each side)
are each approximately 200 µm (8 mil) long. All wire is
17 µm (0.7 mil) diameter gold.
