1. An apparatus comprising:
a radio frequency (RF) receiver section configured to receive a RF signal from a phased array antenna, the RF signal comprising at least a portion of a plurality of data beams included in a single channel;
a plurality of channel separators electrically coupled with the RF receiver section and configured to generate a plurality of channel signals based on the RF signal, wherein generating the plurality of channel signals comprises separating the RF signal into a plurality of channels in which each channel of the plurality of channels includes at least a portion of a respective subset of the plurality of data beams; and
a plurality of signal conditioning components electrically coupled to the plurality of channel separators and configured to decode each data beam of the plurality of channel signals with a respective phase and a respective time delay, wherein the plurality of signal conditioning components outputs the plurality of data beams of the plurality of channels.
