Abstract
(EN)
A payload subsystem of a satellite includes a plurality of transmit antenna feeds, a plurality of frequency filters, and a power amplification arrangement including a plurality of power amplifiers. The power amplification arrangement has at least one multiport amplifier, the multiport amplifier including a plurality of output ports, each output port coupled with a respective one of the plurality of transmit antenna feeds by way of a respective one of the plurality of frequency filters.
