Abstract: An apparatus for converting frequency of signals includes a first switch having a first input terminal to receive a first input signal, a first output terminal, and a second output terminal, wherein the first switch couples the first input terminal to either the first or the second output terminal. A mixer circuit is coupled to the second output terminal, and is to mix the first input signal to a second input signal, to generate a modified input signal. A filter circuit includes a plurality of programmable filters, to receive the modified input signal and output a filtered signal. A second switch has (i) a second input terminal coupled to the first output terminal, (ii) a third input terminal to receive the filtered signal, and (iii) a third output terminal, wherein the second switch is to couple the third output terminal to either the second or third input terminal.
