Optimization on RF devices design applied in wireless communications

Abstract

Third generation (3G) cellular mobile communications demands very strict requirements on transreceptor devices design, in mobile terminal or base station [1]. Particularly, in mobile terminal, design requirements of power amplifier indicate the next parameters: High linearity ( 20 dB), maximum output power (28 dB), by the way of together carry out with the relationship Carrier to Interference (C/I) of 9 dB [2]. In this article, we will present the optimum design of these devices that carrying with such requirements, furthermore, saving more than 20 % of general power consumption in DC
