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.
