Abstract
A signal mixing circuit device and a receiver are disclosed, the signal mixing circuit device comprising first to fourth mixers, first and second signal amplifying circuits, a signal strength detector, a controller and an attenuator. A signal strength value for the output from the first signal amplifying circuit is detected using the signal strength detector. If the signal strength value is less than a first threshold, a high-gain path is initiated, so that noises respectively input to the first and second mixers together with local oscillator signals are eliminated by the fourth and third mixers respectively, thereby ensuring a high signal-to-noise ratio. If the signal strength value is greater than a second threshold, a low-gain path is initiated, which partially reuses the circuit of the high-gain path, thereby effectively reducing the overall circuit area and decreasing chip cost and power consumption.
