Claim 17:
18. A method, comprising:
receiving a mixer input signal;
determining a plurality of frequencies active in the mixer input signal;
configuring a first degeneration component associated with a first mixer forming at least a portion of a harmonic rejection mixer (HRM) based on the plurality of frequencies; and
down-converting the mixer input signal in the first mixer, wherein configuring the first degeneration component of the first mixer comprises:
controlling a first aspect of the first degeneration component to a first value to suppress upconversion harmonics in a first mode or controlling the first aspect of the first degeneration component to a second value to suppress downconversion harmonics in a second mode in response the mixer input signal corresponding to a carrier aggregation combination of a first band and a second band, the first band having one or more harmonics that at least partially overlap the second band.
