KAWASAKI, Japan-Fujitsu Laboratories Ltd said it has developed an amplifier with the world’s highest output for W-CDMA base stations. It is known as a gallium nitride high electron mobility transistor amplifier.
“This breakthrough represents a significant step forward in making smaller and more energy efficient base stations for 3G mobile networks and overcomes the technical hurdle for output needs exceeding 150 watts required for realistic application in 3G mobile systems,” said the company.
