Abstract
A receiver includes a mixer configured to convert a radio frequency (RF) signal into a baseband, an impedance shaping unit configured to shape a magnitude of load impedance seen in an output terminal of the mixer in a frequency band of an interference signal converted into the baseband so as to reduce the magnitude of the load impedance, and a trans-impedance amplifier configured to amplify the signal converted into the baseband.
