Abstract A receiver with built-in low-noise high-frequency amplifier, includes: a high-pass filter, for carry out a high-pass filtering to the high-frequency signal; an antistatic unit, for the prevention of electrostatics contained in high-frequency signals; a low-noise high-frequency amplifier, for using single-gate field-effect transistors to amplify and output the signals when the electric field intensity of the high-frequency signals is weak; a high-frequency switching unit, for bypassing the high-frequency signals when the electric field intensity of the high-frequency signals is high; and a controller, for judging the electric field intensity of the high-frequency signals based on Automatic Gain Control, and outputing control signals to selectively drive a low-noise high-frequency amplifier and a high-frequency switching unit.
