RESUMO
The links of satellites are affected by propagation conditions and distortions that are generated by devices. The propagation losses as well as the passive components attenuation are very simple to analyze, but many calculations involved with the complete link demand to discover the carrier to inter-modulation ratio. This work presents an innovative set of equations to calculate the carrier-to-inter-modulation ratio, with number and amplitude of carriers and features of the transponders. The equations are developed by the finite induction methods and permit to have a very good results of the performance of the satellite with respect to the non-linearity comportment.
