Solving the Heat Problem in Wireless Data Terminals
Overview Standards adopted for next generation cellular communications require increased signal processing loads and also use on-air signals with increasing peak-to-average power ratios. Besides having an increased operating temperature in mobile terminals, because battery technology is progressing at a much slower pace, battery life is also getting shorter. Since it is unacceptable to change the adopted standards, the only option available to achieve comparable battery life to voice-only handsets is to radically change implementation architectures. In the digital domain this implies that the CMOS feature size must progress below 0.1 micron. In the RF domain, this means that linear circuit approaches must be abandoned in favor of nonlinear technologies.
