Self resonant frequency of inductors in a LNA DC bias tee

Carbon_Rod, Mon Sept 25 2017, 07:19AM

Given under DC bias the rated self resonant frequency of chip inductors in a bias tee is somewhat lower.

Is it acceptable practice to still estimate lumped element parallel inductors using the standard model?

Edit: short answer is No.
Depending on the physical proximity, "mutual inductance that exists between two [unshielded] chokes ... may actually reduce the effective coupling" (How to Select R.F. Chokes, May 1966, Electronics World, )
