Image Rejection Ratio (IMRR) with transmit IQ gain/phase imbalance

Krishna Sankar12 years ago3 weeks ago01 mins

The post on IQ imbalance in transmitter, briefly discussed the effect of amplitude and phase imbalance and also showed that IQ imbalance results in spectrum at the image frequency. In this article, we will quantify the power of the image with respect to the desired tone (also known as IMage Rejection Ratio IMRR) for different…
