SEMICONDUCTORS represent a starting point for most circuit and systems
designers. In all their functions (i.e., amplification, frequency tra
nslation, or switching) discrete and integrated-circuit (IC) semicondu
ctors have paved the way for the current explosion in commercial wirel
ess applications throughout the world, In many ways, the pressures of
competition in wireless markets have forced many semiconductor manufac
turers to formulate true long-term marketing and development plans for
the first time.
