Miclab Researchers demonstrated for the first time a dual-band Envelope Tracking  Power Amplifier suitable for 870 MHz and 2140 MHz WDCMA signals. The prototype was based on the GaN HEMT RFMD RF3934 and provided 240 W peak power and 58 % average efficiency.

hold at the Radio Wireless Symposium, the panel session dealt with the impact of ICT technolgy to greenhouse gases emission, and the evolution of telecommunication technology to increase the energy efficienct from now to 2020.
