1. A transmitter system comprising:
a set of modulators comprising (i) one or more first modulators to modulate signals for transmission using a first of multiple polarizations, and (ii) one or more second modulators to modulate signals for transmission using a second of the multiple polarizations, wherein the one or more modulators for each polarization are configured to provide multiple intermediate frequency outputs that overlap in frequency range and carry different data;
a set of upconverters comprising at least one upconverter for each of the multiple polarizations, wherein each of the upconverters is configured to generate a radiofrequency output by concurrently upconverting multiple intermediate frequency inputs to different frequency ranges;
an intermediate frequency distribution network configured to distribute the multiple intermediate frequency output signals from each of the modulators to the inputs of the upconverters; and
a set of radiofrequency switches that are operable to selectively provide the radiofrequency outputs of the upconverters to antenna feeds for the multiple polarizations.
