The recent explosion in mobile applications and the accelerating growth in high speed data devices have dramatically expanded the speed and capacity requirements on wireless networks and the performance demands on mobile devices.
Since high speed data is the backbone of all these applications and high speed data inherently requires significantly more power than voice calls, mobile wireless devices must operate at much higher transmit powers compared to the norm for everyday voice use.
On top of this, the wireless industry is rushing to support new communication standards, most recently 4G/LTE, to support this need for speed and capacity. The complexity of these newer communication schemes and their high peak to average ratio signals make it difficult for today’s PA technology to produce the needed power efficiently, and without distortion.
The wireless industry desperately needs a way to address the need for more transmit power and more efficient PAs. qBoost Envelope Tracking technology fulfills this need by enabling devices to deliver more transmit power and at the same time enable the PA to operate more efficiently when transmitting 3G and 4G/LTE signals.
