Highly integrated Radio-Frequency Front-End for next generation wireless systems

Mobile traffic has been doubling annually, and this exponential growth is set to continue over the next five years. By the end of the decade, the average mobile user could be downloading one terabyte of data each year. To meet this demand, a fifth-generation (5G) cellular technology will need to be developed. The integration of the radio-frequency (RF) front-end, however, presents several challenges that still need to be addressed for the advent of the next generation of wireless communication systems. Current solutions are too expensive and power hungry for portable systems. Also, due to interconnect losses and crosstalk, the integration of passive millimeter-wave components with active integrated circuits is a complex process.
