Mixer Spur Analysis with Concurrently Swept LO, RF and IF: Tools and Techniques

RF/microwave system design engineers must be able to predict mixer spurs that may be detrimental to their system’s integrity. These spurs can be estimated using industry standard frequency ratio spur charts. However, this method is cumbersome and overw...
Assessing mixer spurs reliably can enable first-cut success in communication hardware design with reduced development time and product cost. The tools used to determine these spurs must be able to manipulate LO, RF and IF frequencies concurrently over their continuous bandwidths. These tools can be either standard graphical charts...
