In datasheets like the one of the ADL5320 there is indicated a tuning procedure to optimize for OIP3, OP1dB, gain. How much do I lose by simply putting the passive components next to each other in a space constrained application instead of placing them on the trace 100-300 mils apart as proposed?

    The recommended location given at the Table 7, on the datasheet are the ones that are optimized by simulation and tested for different frequency bands. We have not checked the performance trade-off when you change the locations. Small location changes (50 mil) should not effect the performance.

    It is best to follow DS configuration in order to get the DS performance. It would be best to check and see if the performance of your configuration meets your application requirements.
