Configurable harmonic rejection mixer (HRM)

An apparatus for wireless communication, comprising:

• means for determining a carrier aggregation (CA) configuration of a mixer input signal comprises a carrier aggregation of a first band and a second band having one or more harmonics that at least partially overlap the first band;
• means for controlling a first aspect of a first degeneration component of a first mixer to a first value to suppress upconversion harmonics in a first mode or to a second value to suppress downconversion harmonics in a second mode based on the CA configuration being a first CA configuration or a second CA configuration, respectively, and for controlling a second aspect of a second degeneration component of a second mixer to a third value to suppress upconversion harmonics in the first mode or to a fourth value to suppress downconversion harmonics in the second mode based on the CA configuration being the first CA configuration or the second CA configuration, respectively;
• first means for downconverting the mixer input signal;
• and
• second means for downconverting the mixer input signal.

An apparatus, comprising:

• a first mixer coupled between an output of a low noise amplifier (LNA) and a node at an input to a baseband circuit;
• a second mixer coupled between the output of the LNA and the node at the input of the baseband circuit;
• a first degeneration component coupled between the output of the LNA and the second mixer, the second mixer configured to suppress upconversion of one or more harmonics based at least on a value of the first degeneration component;
• and
• a controller configured to control a first aspect of the first degeneration component in a first mode to suppress upconversion of the one or more harmonics based on determining a signal corresponding to the output of the LNA comprises 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.
