Hi Khalil,
You have not provided enough information for us to provide you with a good answer for any of your three questions.
1. Generally it is not a good idea to use an inductor (as an inductor) above its self resonant frequency because it no long behaves as an inductor. However, we do not know how you intend to use the inductor, so it is difficult for anyone to comment on how the self resonant frequency will impact the performance of your design.
For instance, if the inductor is used primarily for an RF choke, then perhaps it may be ok if the self resonant frequency is within your operating bandwidth.
On the other hand, if the inductor is specifically used for impedance matching then it may not be acceptable.
2. Cadence and ADS are just simulator environments, they will detect whatever the models predict. The accuracy of the models are much more important than the specific tool. So, how is the inductor resonance modeled: s-parameters from EM simulation, factory provided models, etc.?
3. More specific information is needed to answer your question. Are you asking if the bypass and decoupling capacitors need to be supplied on your die or for the probes? Generally it is best to have all your decoupling and by-passing for high frequency signal on the die to keep all high frequency currents local to the die.
Best regards, RFICDUDE
