| Zusammenfassung: | A radio frequency front end, terminal apparatus, and carrier aggregation method. The radio frequency front end comprises: P transmission subcircuits, wherein each of the transmission subcircuits is used to transmit a carrier modulation signal in one of M different frequency bands, and comprises at least one transmission filter, and said transmission filter passes carrier waves in a frequency band consistent with at least one frequency band transmitted by said transmission subcircuit; N receiving subcircuits, wherein each of the receiving subcircuits is used to receive a carrier modulation signal in at least one of the M different frequency bands, and comprises at least one receiving filter, and said receiving filter passes carrier waves in a frequency band consistent with at least one frequency band received by said receiving subcircuit; and a switch circuit having L input ports and at least one output port, wherein the output port is connected to an antenna or an antenna back-end circuit, and the L input por |
