disclosed is a heterodyne receiver for low noise and image frequency repression , comprising : a low noise amplifier for receiving an input signal from an antenna and amplifying the signal while reducing a noise figure of the input signal ; and a frequency converter for receiving both the input signal outputted from the low noise amplifier and a local oscillation signal , filtering the signals to repress gain of the input signal at an image frequency band and increase gain of the input signal at a signal frequency band , and converting the frequency of the signals to the intermediate frequency band .
