The evolution of semiconductor-based radios has
allowed the rapid development of
RF design both for wireless systems and
wireless modules. One advantage of semiconductor
integration is the ability to realize various radio
systems as differential circuits to maximize performance
and yield. However, many wireless systems are single-ended
at the front-end terminals. Regardless if the interface
is single-ended or differential, it is important
to understand the characteristics of a single differential
RF port in terms of Mixed-Mode S-parameters in order
to bridge the two disciplines of RF design engineering
and semiconductor engineering.
