Mismatch calibration method for harmonic rejection mixer architecture and mixing apparatus using the same

摘要

Harmonic mixing device is provided to remove the mismatch compensation method and apply it to the mixer structure . The mixing apparatus , estimates the signal strength and signal phase mismatch mismatch between the two mixer selected one of the plurality of mixers to be compensated . In addition , a signal size mismatch and signal phase mismatch can be compensated by the estimated independently together via a single relational expression , it is possible to reduce the computation required for the mismatch estimation , fast mismatch compensation is possible .
