Abstract
This invention provides a circuit for perfecting the performance of a mobile terminal. The circuit is applied to a radio frequency circuit containing a DC component, the circuit comprises: a radio frequency module provided with a nonlinear device; and an LC parallel resonance circuit, wherein one end of the LC parallel resonance circuit is connected with a nonlinear output end of the nonlinear device, and the other end of the LC parallel resonance circuit is grounded through a first stopping condenser. W hen a signal in the mobile terminal generates secondary harmonic and other nonlinear distortions by the nonlinear device, due to the property of infinite impedance of the LC parallel resonance circuit to the fundamental wave and the short circuit property to the secondary harmonic, the secondary harmonic can be effectively perfected without influencing the fundamental wave. The first stopping condenser connected with the other end of the LC parallel resonance circuit can avoid a DC ground short circuit phenomenon, so that the circuit can be used in the circuit containing the DC component, and then the purpose of perfecting the secondary harmonic of the mobile terminal is achieved.
