So last year physorg.com had a story about saving 50% power consumption just by enhancing content strategies. I’ve been keeping my eyes on that one, therefore when I saw these, my triggers went off. I have about 4 technologies that are not earth shattering but each add up to dramatically slice power consumption for mobile devices. Here goes..
BTW, this latest batch of technology is fundamental and is useful for all 4G LTE devices being used in most any way.
Firstly. there is a company called Quantance that has introduced a seriously kick butt power amplifier device for UEs. Their Q845 is a single chip 0.18μm component that enables Envelope Tracking (ET) for power amplifiers (PA) therefore, when combined with a relatively efficient PA component the effective power efficiency can approach 50% vs typical 35% seen in today’s designs. Here is their nifty graphic that shows the benefits:
Quantance calls their ET technology qBoost. This is a significant improvement for LTE mobile radios. Don’t forget that this ET approach improves linearity of the PA. This will be realized as greater dBs TX power and improved Error Vector Magnitude (EVM) for greater throughputs in the uplink at the reduced power.| | | Next → |
