Direct conversion receiver (homodyne); Direct conversion receiver

A direct conversion (homodyne) receiver architecture is a configuration that transposes the reception band directly into the baseband (BB) and uses low-pass filters to eliminate adjacent interference.

Radio Frequency Front End; RF Front End

In a radio receiver, a radio frequency front end is a generic term for all circuits between the antenna input of a receiver up to and including the mixer stage. It includes all circuits in the receiver that process the signal at the initial radio frequency input, before it is converted to a lower intermediate frequency (IF).

RF mixers; RF mixer

RF mixers or frequency mixers are passive or active three-port microwave circuits capable of creating new frequencies when two signals are applied to them. The two input frequencies, called RF and LO, are modulated inside...
