Abstract: The present invention provides a radio frequency channel, including: a first antenna, a low noise amplifier, a power divider, at least two first single-pole, n-throw switches, at least four first filters, and at least two first radio frequency chips. The power divider divides a received radio frequency signal into two first radio frequency sub-signals, and transmits the two first radio frequency sub-signals to the at least four first filters, where the at least four first filters correspond to at least four filtering bands and the at least four first filters may cover frequency bands involved in at least six carrier aggregation CA technologies, the at least four first filters filter the first radio frequency sub-signals, and the at least two first radio frequency chips process the filtered first radio frequency sub-signals.
