Multi-channel, multi-band linearized digital transceivers

A device for wireless communication, comprising:

• a radio frequency (RF) front end configured to receive an incoming analog RF signal associated with a receive path and configured to transmit an outgoing analog RF signal associated with a transmit path;
• a mixed-signal front end coupled to the RF front end, the mixed-signal front end configured to convert the incoming analog RF signal into an incoming digital RF signal;
• and a plurality of transceivers coupled to the mixed-signal front end, each of the plurality of transceivers configured to process the incoming digital RF signal to provide an incoming baseband processing signal associated with the receive path and configured to process an outgoing baseband processing signal to provide an outgoing digital RF signal associated with the transmit path,
• wherein the device is configured to:
• combine the plurality of outgoing digital RF signals from the plurality of transceivers into the composite outgoing digital RF signal;
• determine a loading value based on the composite outgoing digital RF signal;
• and
• process the composite outgoing digital RF signal based on the loading value, and
• wherein the mixed-signal front end is configured to convert the processed composite outgoing digital RF signal into the outgoing analog RF signal.

An apparatus for wireless communication, the apparatus comprising:

• means for processing a plurality of outgoing baseband processing signals, each of the plurality of outgoing baseband processing signals being associated with a sub-band of a plurality of baseband sub-bands;
• means for converting the plurality of outgoing baseband processing signals into a plurality of outgoing digital radio frequency (RF) signals;
• means for combining the plurality of outgoing digital RF signals into a composite outgoing digital RF signal;
• means for determining a loading value based on the composite outgoing digital RF signal;
• means for processing the composite outgoing digital RF signal based on the loading value;
• means for converting the processed composite outgoing digital RF signal into an outgoing analog RF signal;
• and
• means for providing, for transmission, the outgoing analog RF signal.
