Problems solved by technology

[0017] In the above scheme, the 9-channel antenna switch used is more expensive due to less production.
At the same time, this solution is used to control the general-purpose input and output GPIO interfaces of radio frequency devices, which is a waste of resources in the context of tight GPIO resources in the current user terminal system.

Abstract

The invention relates to a dual-mode radio frequency module, comprising a GSM radio frequency transceiver and a TD-SCDMA radio frequency transceiver, connected to an antenna, wherein, a 4-channel antenna switch is connected to a GSM radio frequency front end, and the GSM radio frequency front end is connected to the GSM radio frequency transceiver to send signals; The GSM RF front-end is connected to two single-pole double-throw RF switches, and is connected to the GSM RF transceiver through the SAW filter to receive the signal, or the GSM RF front-end is connected to two single-input and double-out SAW filters, through two single-input and double-out The SAW filter is connected to the GSM radio frequency transceiver to receive signals, and the GSM radio frequency front end includes a low frequency transmitter, a high frequency transmitter, a low frequency receiver and a high frequency receiver. The invention also provides a radio frequency receiving and sending method and a user terminal. By adopting the technical solution of the invention, the design cost of the hardware is saved, and the resource utilization rate is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a radio frequency module, a radio frequency receiving and sending method and a user terminal. Background technique [0002] TD-SCDMA (TimedivisionsynchronousCDMA, Time Division Synchronous Code Division Multiple Access) referred to as TD, as one of the three major 3G standards, it combines the technical advantages of TDD (TimeDivisionDuplexing, Time Division Duplex) and CDMA (CodeDivisionMultipleAcess, Code Division Multiple Access), It has a flexible air interface, and adopts advanced technologies such as intelligent antenna and joint detection, which make TD-SCDMA quite advanced in technology, and has the highest spectrum efficiency among the three standards. With the step-by-step resolution of issues such as wide-area coverage and high-speed mobility, TD-SCDMA will become a satisfactory 3G solution that can be obtained at the most economical cost. [0003] According to the...
