摘要：

This paper discuss the suitability of using a MultiPort Amplifier (MPA) for multimedia multi-beam telecommunication operation with power flexibility requirements. With this aim, a Ka-Band MPA has been characterized in a realistic environment for telecommunication operation. Simulation and measurement results are discussed and the performances of the MPA based architecture and a classical architecture (with one power amplifier per beam) are compared in terms of power consumption. The MPA proves to be an interesting solution since it offers flexibility with lower power consumption and less equipment.
