Abstract：
The invention provides a software radio receiver circuit. The software radio receiver circuit comprises a low-noise radio-frequency front end circuit, a high-linearity radio frequency front end circuit, a harmonic attenuation radio frequency front end circuit, a common analog intermediate-frequency circuit, a local oscillator signal generation circuit, a biasing circuit and a control circuit. One end of the low-noise radio-frequency front end circuit is connected with the first end of the common analog intermediate-frequency circuit after the low-noise radio-frequency front end circuit is connected with the high-linearity radio frequency front end circuit in parallel. One end of the harmonic attenuation radio frequency front end circuit is connected with the first end of the common analog intermediate-frequency circuit .The local oscillator signal generation circuit is connected with the low-noise radio-frequency front end circuit, the high-linearity radio frequency front end circuit and the harmonic attenuation radio frequency front end circuit. The biasing circuit is used for providing a reference bias voltage and a reference bias current for the software radio receiver circuit. The control circuit is used for controlling work modes of the software radio receiver circuit. The software radio receiver circuit can meet the requirements of various application environments.
