Abstract: A radio frequency (RF) integrated circuit is provided. The RF integrated circuit supports carrier aggregation and includes first receiving circuits and a first shared phase locked loop circuit that provides a first frequency signal of a first frequency to the first receiving circuits. One of the first receiving circuits includes an analog to digital converter (ADC) and a digital conversion circuit. The ADC converts an RF signal received by the one of the first receiving circuits to a digital signal by using the first frequency signal. The digital conversion circuit generates a digital baseband signal by performing frequency down conversion on the digital signal.
