Problems solved by technology

But the problem with this solution is that it increases the number of antennas
Due to the increasing number of mobile phones with all-metal back covers, the design of the antenna is more difficult under the premise of the appearance design of the all-metal back cover, and there are strict requirements on the number of antennas. It is impossible to stack many antennas like the plastic mobile phone back shell.

Abstract

The invention provides a radio frequency circuit and a terminal for realizing carrier aggregation. The radio frequency circuit for realizing the carrier aggregation comprises a first antenna used for realizing power transmission and master set receiving of a signal of a first frequency band and a signal of a second frequency band; a second antenna used for receiving power transmission and receiving of a signal of a public frequency band, and realizing power transmission and master set receiving of a signal of a third frequency band and a signal of a fourth frequency band; a third antenna used for realizing diversity receiving of the signal of the first frequency band, the signal of the second frequency band, the signal of the third frequency band and the signal of the forth frequency band; and a transceiver, which is connected to the first antenna, the second antenna and the third antenna through a signal processing circuit, and is used for realizing the carrier aggregation of the first frequency band and the third frequency band, and the carrier aggregation of the second frequency band and the fourth frequency band. The radio frequency circuit and the terminal for realizing the carrier aggregation provided by the invention can realize the carrier aggregation on the premise of not increasing the quantity of existing terminal antennas, and can reduce the power consumption and cost when the terminal realizes the carrier aggregation.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular, to a radio frequency circuit for realizing carrier aggregation and a terminal. Background technique [0002] In order to meet the explosive growth of data services and user perception requirements when using new services, mobile operators are actively deploying 4G+ with carrier aggregation (Carrier Aggregation, also known as 4.5G) network to improve user experience. At present, almost all leading LTE (Long Term Evolution, Long Term Evolution) operators are actively deploying carrier aggregation to aggregate and use limited spectrum resources as much as possible. [0003] Currently, China Mobile, China Unicom and China Telecom are actively upgrading their networks and deploying carrier aggregation. Since China Mobile belongs to TDD (TimeDivisionDuplexing, Time Division Duplexing)-LTE, which requires B39+B41 carrier aggregation, frequency dividers are usually used for...
