    摘要： A receiver and a low noise amplifier are provided. The receiver includes a primary signal pathway, an auxiliary signal pathway, a combiner circuit, and an intermediate frequency amplifier circuit. The primary signal pathway includes a gate series inductor, a first common-source amplifier circuit, and a frequency mixing circuit, where an input end of the primary signal pathway is connected to an input end of the first common-source amplifier circuit by using the gate series inductor, an output end of the first common-source amplifier circuit is connected to an input end of the frequency mixing circuit, an output end of the frequency mixing circuit is connected to a first input end of the combiner circuit, and an output end of the combiner circuit is connected to an input end of the intermediate frequency amplifier circuit. The auxiliary signal pathway includes a second common-source amplifier circuit and a frequency mixing and phase shift circuit, where an input end of the auxiliary signal pathway is connected to an input end of the second common-source amplifier circuit, an output end of the second common-source amplifier circuit is connected to an input end of the frequency mixing and phase shift circuit, and an output end of the frequency mixing and phase shift circuit is connected to a second input end of the combiner circuit. The solutions in this application help improve system integration and implement a lower noise figure.
