RFMD: GaN-based broadband power amplifier world's most efficient
A broadband power amplifier design by RFMD and Nujira can transmit over the 728-960 megahertz band with more than 50 per cent efficiency.
The so-called world s most efficient broadband power amplifier (PA) design for 4G base stations is set to be demonstrated at the Mobile World Congress in Barcelona later this month by RF Micro Devices (RFMD) and Nujira.
It marks an integration of RFMD s high-performance gallium nitride (GaN) amplifiers of the RFG1M family with Nujira s Coolteq.h envelope tracking power modulators.
RFMD s GaN devices can enable the entire cellular spectrum of 700 megahertz to 2,700 megahertz to be covered but with a reduced number of PA platforms.
The integrated PA design can transmit over the 728-960 megahertz band with more than 50 per cent efficiency, requiring just one Coolteq.h module with one RFG1M device.
Using future GaN devices which RFMD is currently developing can allow the entire cellular spectrum to be covered with three broadband PAs, helping to meet transmission standards of wireless infrastructure vendors.
"Expect to see GaN, coupled with envelope tracking, in many new RRH designs," stated Lance Wilson, research director for radio frequency components and systems at ABI Research.
RFMD recently announced it was to release further GaN power products in the three months to the end of March 2010.
