Abstract
(EN)
Disclosed in embodiments of the present invention are a radio frequency transmission circuit and circuit matching method. The radio frequency transmission circuit comprises: a control unit and at least one transmission loop unit. The transmission loop unit comprises at least one predetermined matching loop, and the control unit is pre-stored with a correspondence relationship between predetermined transmission powers and the predetermined matching loops. The control unit is used to determine, according to the pre-stored correspondence relationship between the predetermined transmission powers and the predetermined matching loops, a predetermined matching loop corresponding to the received transmission power as a first matching loop, and control the first matching loop to operate. Also provided in the embodiments of the present invention is a computer storage medium.
