Power Distribution in Portable Two-Way Radio Design Efficiency Improvement

In the 2-way radios market, long battery life has becomes an essential & critical customer requirement for communications during critical public safety or rescue missions. Thus in tandem with this need, various researches have been conducted by industry players to reduce the current consumption of the design with minimum sacrifices on product performance. This paper attempts to describe various key strategies that can be adopted in the design of portable two ways radio design in optimizing the efficiency of the power distribution network in the radio and design guidelines on selection and implementation of switching regulator in radio to reduce the overall current drain consumption.
