LO Harmonic Effect of I/Q Modulator Sideband Suppression

Texas Instruments

Published Date: 05/10/2010

Description

This report describes the effect that high local oscillator (LO) harmonics have on the I/Q balance of a complex (I/Q) modulator. The imbalance that is generated has a direct impact on sideband suppression performance of the I/Q modulator. This application report discusses the theoretical distortion generated by the harmonics along with measured results showing the effect on sideband suppression
