In carrier aggregation, more than one component carrier is allocated to a single User Equipment (UE), or subscriber.

The baseband data, whether it is OFDM, OFDMA, or SC-FDMA, is passed through a Digital-to-Analog Converter (DAC) and then up-converted based on the allocated frequency band and the desired sampling frequency, which depends on the bandwidth. The reverse operation, Analog-to-Digital Conversion (ADC) and down-conversion, takes place in the receiver part of the carrier aggregation circuit.

The figure below depicts the transmitter part. To combine the power spectrum of the component carriers, a power combiner circuit is used, with the number of inputs depending on the number of component carriers. Here, a 2-to-1 power combiner is shown.
