3 Summary

RF droop estimation and applied correction for each band enabled improve the amplitude flatness across the frequency range of interest.

We can summarize from the test data that the profile of amplitude across the frequency up to the second order can be corrected with the aforementioned method to required specifications. The frequency response can be caused due to internal or external factors of the device. With correct inputs to the rf droop macro, the response can be corrected digitally to meet the specifications required, given the error is within the mentioned limit.
