Improve The Design Of Your Passive Wideband ADC Front-End Network
As converter technology improves, so does the demand to resolve very high intermediate frequencies (IFs) accurately at high speeds. This poses two challenges: the converter design itself and the front-end design that couples the signal content to the converter. Even if the converter itself is excellent, the front end must be able to preserve the signal quality too.
