Abstract :
An analog mobile phone is described and broken down into basic technological requirements for each block. Silicon integration with enhanced speeds/densities of a single technology as well as with mixed technologies and signal-processing based design are considered. New requirements of operation in the 2-GHz frequency range and high bit rates for time-division multiple access, frequency-division duplex, or time-division duplex (TDMA, FDD, or TDD) systems are described. Directions for development are given. The question to which extent cellular mobile telephones (CMTs) will use ASICs or standard ICs is addressed
