Excellent
Hmmm, have not the time to check, but this sounds a lot like Bob Carver’s old Sunfire Cube amp technology - playing with the power supply in an audio amp to increase efficiency and (as a byproduct) decrease the size. Not sure if he varied powersupply voltages to the output stage, or if he was using some sort of digital switching...but methinks he might be have been 20 years or so ahead of these folks.
This will have far more applications than just cell phones.
Just about every month we hear this kind of news. This is the magic discovery for the month of November. Then golden silence.
there is so much bad science in this article.
Battery life has NOTHING to do with amplifier technology.
The article should be titled ‘more efficient RF power amplifier developed’
And, BTW, I don’t believe the claim either. If you want super efficient, low power RF, we already have that technology, it’s just that the cell providers don’ t use it.
Not a technology problem, a business issue.
