Abstract

The invention discloses a radio frequency front end terminal, and further discloses terminal equipment comprising the radio frequency front end terminal. The radio frequency front end terminal comprises a power amplifier, a first single-pole M-throw switch and an N-frequency band matching circuit, wherein M is larger than or equals to N, N is larger than or equals to 2, and both M and N are positive integers respectively; the output end of the power amplifier is connected with the movable end of the one-pole M-throw switch, the stable ends of the one-pole M-throw switch are respectively connected with an input end of the frequency band matching circuit, the control end of the one-pole M-throw switch is connected with the logic output end of a logic control chip of the radio frequency front end module, and the output ends of the N-frequency band matching circuit are jointly connected with an antenna connected to the position outside the radio frequency front end module. Because automatic switching of all frequency bands is achieved under the situation that one power amplifier is adopted, the design complexity of the radio frequency front end module supporting a plurality of modes and a plurality of frequency bands is reduced, and wiring space in mobile terminal internal circuits is saved.

Description

technical field [0001] The present disclosure relates to the technical field of mobile terminal radio frequency, in particular to a radio frequency front-end module and terminal equipment. Background technique [0002] The radio frequency front-end module is an important radio frequency component that cannot be integrated by the transceiver in the mobile terminal at present. In the RF front-end module, the modulated RF signal is amplified to a certain power value through a power amplifier. Then the amplified radio frequency signal is sent out through the antenna. [0003] Telecom operators have launched many different wireless communication systems and adopted different wireless communication standards. The operating frequency and operating mode requirements of the communication system are different under different communication standards. In order to enable the mobile terminal to be used on a global scale, various mobile communication standards must be supported at the s...
