WebJul 23, 2015 · The balun (balanced/unbalanced) is a simple-looking passive component with an almost trivial schematic which resolves the challenge by transforming one signal configuration into the other, and can be used in either direction. WebJul 23, 2015 · 5) Digital Compensation. This is the ultimate in IQ compensation techniques. As we have seen with fiber optic links, wireless links, and any other modern data standard, it is easier and cheaper to use millions of transistors to digitally compensate for a bad signal than to create the analog channel necessary for a good signal.
