Vector Modulation and Frequency Conversion Fundamentals
Agilent in Aerospace/Defense – Webcast Series
Title: Vector Modulation and Frequency Conversion Fundamentals
Date: July 18, 2013
Presenter: John Hansen, Senior Application Engineer, Agilent Technologies
Many applications in communications and radar require modulation of vector signals with I and Q baseband components. As systems become more complex, these modulated signals become wider in bandwidth, higher in carrier frequency and more sensitive to imperfections in the modulation. This presentation will cover different ways to optimize the baseband signal path to minimize the effects of I and Q signal-path mismatches. It will explore different IQ modulation techniques and compare the advantages and disadvantages of each. It will also address methods for up conversion of vector-modulated IF waveforms.
Engineers and system designers that use vector modulation or frequency conversion in their work and during test and evaluation.
