Abstract

The invention provides a control circuit and terminal. The control circuit comprises a diversity radio frequency (RF) path, a main set RF path and a control module; the signal receiving end of the diversity RF path is connected with an upper antenna via the control module, and the control module is used to reduce nonlinear harmonic waves of the diversity radio frequency path; and the signal emitting end of the main set RF path is connected with a lower antenna. Thus, the control module can reduce nonlinear harmonic waves of the diversity radio frequency path, deteriorated stray of the nonlinear harmonic waves can be reduced, and the communication quality of the terminal is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control circuit and a terminal. Background technique [0002] With the rapid development of terminal technology, the terminal has become an indispensable tool in people's life, and has brought great convenience to all aspects of the user's life. Generally, there are main radio frequency path and diversity radio frequency path on the terminal. The signal transmitted by the main radio frequency path can be coupled to the diversity radio frequency path. Since there are nonlinear devices in the diversity radio frequency path, nonlinear harmonics will be generated. The non-linear harmonics seriously deteriorate the spurious phenomenon, resulting in poor communication quality of the terminal. Contents of the invention [0003] Embodiments of the present invention provide a control circuit and a terminal, so as to solve the problem that the non-linear harmonics of th...
