Direct conversion receivers perform the RF to baseband frequency translation in a single step.Direct conversion receivers perform the RF to baseband frequency translation in a single step.  The RF signal is mixed with a local oscillator at the carrier frequency thus eliminating any image components to cause signal corruption.   Today these homodyne or direct conversion receivers are typically only used where modulation methods do not put any significant signal energy near direct current.
