Abstract
A system and method for frequency-agnostic multiband aggregation of received signals is disclosed for use in high capacity communication. The system includes two up-conversion mixer stages and one down-conversion mixer stage, with SAW filter banks or other band pass filter banks used to select frequency bands of interest for aggregation based on configurable multiband combination settings. The method provides for the design of optimal multiband aggregation configuration settings.

A system for multi-band communication, the system comprising:
- at least one receiver branch, each receiver branch comprising:
- a band-isolation stage comprising a plurality of sections, each section comprising:
- a band-isolation stage mixer configured to receive a band-isolation stage input signal and down-convert the band-isolation stage input signal to a band-isolation stage frequency value;
- and
- a filter bank comprising a plurality of band pass filters and configured to:
- select one of the plurality of band pass filters based on received configuration instructions;
- and
- route the down-converted signal through the selected band pass filter.

A method for multi-band communication comprising:
- receiving configuration instructions at a plurality of band-isolation stage sections;
- receiving a band-isolation stage input signal at the plurality of band-isolation stage sections;
- and
- at each band-isolation stage section:
- down-converting the band-isolation stage input signal to a band-isolation stage frequency value;
- selecting one of a plurality of band pass filters based on the received configuration instructions;
- and
- routing the down-converted signal through the selected band pass filter to propagate a frequency band of the received band-isolation stage input signal.
