Re: MMIC Amplifier Bias calculation
If the inductor has a core material other than air, such as powdered iron
or ferrite (and it probably does), the DC current through it could saturate
the core material. That would cause the inductor to become non-linear or
have much lower than marked inductance.
If you know the manufacturer and part number of the inductor you might be
able to look up what value of current would cause it to saturate. Otherwise
you could wind your own inductor on a toroid and use published values of
its properties to be sure you're avoiding saturation.
