Cree, Inc.  (Durham, NC) [Nasdaq: CREE ] and Eta Devices, Inc. (Cambridge, MA) have announced their power amplifier for mobile base stations. Current generation mobile base station amplifiers employing silicon LDMOS transistors can provide amplifier efficiencies up to 45 percent.
By contrast, Eta Devices’ next-generation power amplifiers are able to deliver efficiencies higher than 70 percent under a 4 G LTE modulation format, and are thus poised to revolutionize current industry efficiency standards.
The world’s mobile networks consume approximately 120 TWh of electricity per year, and 50-80 percent of these networks’ power is consumed by their power amplifiers and associated components.
Implementing Eta Devices’ new power amplifier solution on a global level could save mobile operators 60TWh of energy per year, which is equivalent to the amount of power produced by more than seven average-sized American nuclear power plants. It could also save up to 50 percent of the $36.5 billion spent to power mobile base stations each year.
