Ok Jim. You're asked about the stray components hidden in the real
parts/circuit.

There is nothing hidden at all. Strays are a part of the real life at VHF
and above. Sometimes strays have more effect than the part itself.



If you take the values from the datasheets for die and/or
package or give it a guess if not available, and add values for the pcb
lines, you have a good simulation result.

Horsefeathers. What "values" do you add for the pcb lines?



Lumped L and C if things are slow, or a hunk of transmission line when
things get fast. Works fine.
