Mobile radio telephony is becoming a driving application for analog circuit design and silicon CMOS and RF bipolar technology. New telecom systems like GSM, PCN, DECT, Wireless in the loop ... are all developing very rapidly and will enable us very soon to organise a complete telephone network with full coverage for your mobile car phone, as well as in your kitchen and on your office desk. In Europe the major telecom companies have worked together to establish one common standard for cellular mobile radio communications at 900MHz. Similar things are happening for other wireless personal communication systems. Basically the cellular radio telephone, the wireless PABX and the wireless SLIC are bringing the same challenges to analog circuit design: maximum integration of the basic radio functions into 1 or 2 silicon chips, CMOS, Bipolar or BICMOS or GaAs.
