“…Mid-and long-term a flexible power to beam allocation, depending on the required capacity of the spot, will be realised using matrix power amplifiers [10] and switch matrices [11]. Short-term, until space qualified flexible Kaband payload becomes available, different spot diameters can be chosen to account for different capacity needs.…”

Ka-band payloads are becoming more and more popular for satellite communication. The wider band width in Ka-band allows a better satisfaction of the increasing demand for capacity. In addition to the use of more resources, a more efficient use of the available resources will become key for a successful development of satellite communication services. Modern antenna concepts allow a high frequency reuse scheme and, therefore, an extreme efficient use of the most rare resource in satellite communication, the frequency band width. In this paper, we describe the design and the use of different types of such antennas.

“…MPAs provide a significant higher flexibility for the power to beam allocation of multi spot beam satellites. They need orthogonal input and output networks, which are usually realised using branch-line couplers [4].…”
