ABSTRACT:
A system and method for frequency conversion in a frequency-conversion receiver is disclosed. The frequency-conversion receiver receives input RF signals carrying multiple channels. The frequency-conversion receiver converts the input RF signals to a wide IF band. The IF band is further processed by dividing the IF band into one or more frequency segments or by selecting a wideband frequency segment from the IF band. The wideband frequency segment or the one or more frequency segments are further down-converted, filtered and amplified to provide desired output IF signals, based on the number of channels required in the output IF signals.
