Claim 15:
16. An apparatus to reduce spurs in signal conversion, the apparatus comprising:
a first converter configured to generate a first converted output component signal from an input signal;
a first balun configured to provide a differential input of the input signal to the first converter;
a signal inverter configured to generate an inverted input signal from the input signal;
a second converter configured to generate a second converted output component signal from the inverted input signal, wherein the first converter and the second converter are embedded within a single integrated circuit;
a second balun configured to provide an inverted differential input of the inverted input signal to the second converter; and
an output combiner configured to generate a converted output signal with reduced spurs by subtracting a spur in the first converted output component signal from a corresponding spur in the second converted output component signal.
