Further addressing small values of inductance: There is really no need to
buy SM inductors which may or may not be apropriate. Small nH inductors
can easily be made of short lengths of appropriate single conductors. For
example and one I always remember is that AWG #18 solid copper wire
exhibits 18.1 nH / inch. The following calculator may be of use for this
purpose:

Nico,
So you have two issues here...
Th first one is that you will have difficulty knowing what the impedance
is near the matching network because your measuring system is affecting the
results. That was the point of my previous post.
The second is that even if you knew precisely what impedance you are
trying to match inductors and capacitors at 916 MHz. will not have the same
values as they do at lower frequencies. An inductor will have series
resistance that increases with frequency and parallel capacitance. A
capacitor will have lead inductance. So you need to purchase components
that have been characterized at 900 MHz.
