Abstract

A transmitter architecture and methodologies supporting uplink inter-band carrier aggregation (CA). In various embodiments, first and second baseband signals are provided to a plurality of passive mixers that selectively combine the baseband signals with differing local oscillation signals to produce outbound RF signals of at least first and second RF frequencies. Depending on the relevant CA mode of operation, the outbound RF signals are amplified and selectively coupled to at least one transmitting antenna for respective transmission over a plurality of frequency bands.

First claim

What is claimed is:

1. A wireless communication device comprising:
digital processing circuitry configured to:
divide digital data into a first digital information signal and a second digital information signal; and
generate a carrier aggregation control signal based upon a carrier aggregation mode of operation;
first baseband circuitry configured to convert the first digital information signal into a first baseband signal;
second baseband circuitry configured to convert t…
