Abstract

The embodiment of the invention provides a radio frequency circuit and a mobile terminal. The radio frequency circuit comprises a filter, a matching module and a standing wave regulator, wherein the output end of the filter is connected with the input end of the matching module, and the standing wave regulator is connected with the output end of the filter and the input end of the matching module; when the load of the mobile terminal is antenna, the standing wave regulator regulates the standing wave of the load of the filter, and the matching module matches the phase of the output end of the filter, so that impedance of the output end of the filter keeps matching with that of the load of the filter. When the load of the mobile terminal is the antenna, the radio frequency circuit provided by the embodiment of the invention can ensure that the impedance of the output end of the filter in the mobile terminal always keeps matching with that of the load of the filter, efficiency and output power of a power amplifier are improved, and electricity consumption and heat productivity of the mobile terminal in a coupling state are effectively reduced, and the radio frequency circuit is simple in structure, small in occupied space and insertion loss, and low in cost.

Description

technical field [0001] The invention relates to the technical field of circuits, in particular to a radio frequency circuit and a mobile terminal. Background technique [0002] Mobile terminals are usually in a conducting state or a coupled state. Wherein, when the mobile terminal is in the conduction state, the load of the mobile terminal is an instrument. In this state, the load emission coefficient of the mobile terminal is very small, and the port impedance of the mobile terminal almost completely matches the port impedance of the instrument. When the mobile terminal is in the coupled state, the load of the mobile terminal is the antenna, and the standing wave of the load of the mobile terminal is relatively large, and the port impedance of the mobile terminal and the port impedance of the antenna do not match seriously. The load impedance mismatch of the mobile terminal will cause the load impedance mismatch of the power amplifier, the efficiency and output power of th...
