Radio frequency (RF) and analog mixed-signal (AMS) technologies serve the very rapidly growing wireless communications market and represent essential and critical technologies for the success of many semiconductor manufacturers. Communications products are becoming key drivers of volume manufacturing. Consumer products now account for over half of the demand for semiconductors. For example, third generation (3G) cellular phones now have a much higher semiconductor content and now are 50 % of the cellular phone market compared to only 5 % of the market a few years ago. The consumer portions of wireless communications markets are very sensitive to cost. With different technologies capable of meeting technical requirements, time to market and overall system cost will govern technology selection. We discuss the technology requirements, difficult challenges, and potential solutions for RF CMOS, bipolar, MEMS, and passive devices for carrier frequencies between approximately 0.8 GHz and 10o GHz.
