Abstract
A receiver includes a radio frequency metal-oxide-semiconductor amplifier, a mixer, and an intermediate frequency amplifier. The radio frequency metal-oxide-semiconductor amplifier is used for receiving amplifying a signal of a first band and a signal of a second band of a satellite microwave band from an external antenna circuit according to a control signal. The mixer is coupled to the radio frequency metal-oxide-semiconductor amplifier for reducing the signal of the first band to a signal of a first intermediate frequency band according to a first oscillation frequency of a local oscillator, or reducing the signal of the second band to a signal of a second intermediate frequency band according to a second oscillation frequency of the local oscillator. The intermediate frequency amplifier is coupled to the mixer for amplifying and outputting the signal of the first intermediate frequency band and the signal of the second intermediate frequency band.
