ActiveCN106877892AImprove the ability to resist strong signal intermodulation interferenceNo nonlinear distortionTransmissionNonlinear distortionUltrasound attenuation
The invention provides an anti-interference receiving circuit structure and method. A power detection module and a power control module are connected between a filter and an amplifier. The power detection module is used for detecting the power of an input signal. The power control module is used for storing a preset power threshold value, and judging whether the detection result of the power of the input signal exceeds the preset power threshold value or not, and carrying out the corresponding power attenuation processing of the power of the input signal. The structure and method can detect a strong interference signal, avoid the amplifier saturation or nonlinear distortion through the attenuation of strong interference power, improve the capability of a receiver for resisting strong signal interference, and guarantees the normal receiving under the strong interference.
