Abstract: A wireless receiver according to the present invention includes a low noise amplifying unit which amplifies a wirelessly received signal with a low noise, a frequency mixing unit which mixes the signal outputted from the low noise amplifying unit with a local frequency outputted from a local oscillator and outputs the mixed result, an intermediate frequency band pass filter which filters the signal outputted from the frequency mixing unit, and a variable gain amplifying unit which amplifies or attenuates the signal outputted from the intermediate frequency band pass filter with a preset level and inputs the amplified or attenuated signal to an analog to digital converter. The wireless receiver further includes a bias unit which shorts the local frequency inputted to the frequency mixing unit.
