AMultiport Amplifier (MPA) is an implementation of the satellite power amplification section that allows sharing the payload RF\r\npower among several beams/ports and guarantees a highly efficient exploitation of the available DC satellite power. This feature\r\nis of paramount importance in multiple beam satellite systems where the use of MPAs allows reconfiguring the RF output power\r\namong the different service beams in order to handle unexpected traffic unbalances and traffic variations over time. This paper\r\npresents Monte Carlo simulations carried out by means of an ESA in-house simulator developed in Matlab environment. The\r\nobjective of the simulations is to analyse how the MPA performance, in particular in terms of isolation at the MPA output ports, is\r\naffected by the amplitude and phase tracking errors of the high power amplifiers within the MPA.
