TERMINAL DEVICE

A terminal device includes a first antenna, a second antenna, a first channel electrically connected to the first antenna, and a second channel electrically connected to the second antenna. The first channel includes at least two first transmitting branches used to transmit carrier signals for carrier aggregation (CA). The second channel includes a receiving branch electrically connected to the second antenna and a receiving filter electrically connected to the receiving branch. The receiving branch may be used to receive CA signals through the second antenna, and the receiving filter may be used to filter the CA signals to obtain the carrier signals for CA. 1. A terminal device , comprising:a first antenna, a second antenna, a first channel electrically connected to the first antenna, and a second channel electrically connected to the second antenna, wherein:the first channel comprises at least two first transmitting branches which are used to transmit carrier signals for carrier aggregation (CA) through the first antenna; andthe second channel comprises a receiving branch electrically connected to the second antenna and a receiving filter electrically connected to the receiving branch, wherein the receiving branch is used to receive CA signals through the second antenna, and the receiving filter is used to filter the CA signals to obtain the carrier signals for CA.2. The terminal device according to claim 1 , wherein the first channel comprises a switch circuit claim 1 , one terminal of the switch circuit is electrically connected to the first antenna claim 1 , and the other terminal of the switch circuit is electrically connected to the first transmitting branches; andthe at least two first transmitting branches comprise transmitting filters, one terminal of each said transmitting filter is electrically connected to said other terminal of the switch circuit, and the other terminal of each said transmitting filter is electrically connected to a radio frequency ...
