On the isolation performance of MPAs in satellite transponders

摘要

This paper presents Monte Carlo simulations carried out by means of an ESA in-house simulator developed in Matlab environment. The objective of the simulations is to analyze how the MPA performance, in particular in terms of isolation at the MPA output ports, is affected by the amplitude and phase tracking errors of the high power amplifiers within the MPA. Different approaches are considered and their results are compared from an end user perspective.
