Abstract :
The aim of this paper is to focus on the dual band power amplifier design and characterization as an enabling technology for beyond 3G wireless systems. The design approach within a full characterization of the dual band power amplifier is given in the paper. For 1.98 GHz 3GPP UL WCDMA and 3.42 GHz 5 MHz 16QAM WiMAX digital systems, the dual-band concurrent exhibited simultaneous peak power levels of 24 dBm and 17 dBm respectively, to maintain ACPR and EVM within the regulatory requirements. A performance discussion is then outlined with respect to multi band multi module PA architectures for software defined radio wireless transmitters.
