MULTICARRIER POWER AMPLIFICATION TECHNOLOGY PROJECTED TO SAVE GSM PROVIDERS UP TO $30 MILLION PER NETWORK
Examples of these benefits include savings of approximately $30million for an average 10,000 base station network. Third Generation (3G) network operators that utilise this technology will benefit from the ability to share power amplifiers in an infrastructure sharing arrangement (multiple operators sharing common equipment). “BTG’s business focus is finding and developing technologies with significant commercial value in growing markets. The trend towards infrastructure sharing in Europe and increasingly elsewhere, combined with the need to capitalise on existing GSM investments, demonstrated the need for a better multicarrier technology,” said Anthony V. Lando, executive vice president and director of BTG’s Electronics, Engineering and Information Technologies division. “We believe that this is a true breakthrough technology and companies who choose to seek a license from BTG will be provided with intellectual property protection, know-how and access to the inventors.” Infrastructure sharing is on the rise in Europe, in part because it enables mobile network operators to save money by sharing network equipment. In many cases this reduces the need for multiple antennas on a landscape where open space is at a premium - concerns that are of importance to US providers as well. The worldwide growth in the telecommunications market for multicarrier power amplifiers has been exceptional. Today’s total annual market for power amplifiers is estimated to be in excess of $1.5 billion and, until recently, has been growing at a rate of 25 percent per annum. The power amplifier market will resume its growth once the economy for cellular equipment improves. “We have been researching radio power amplifiers for over ten years, looking for a design approach that would give us reliable and extremely wide-band linearisation. The key turned out to be an adaptive multi-branch structure,” commented Jim Cavers, professor of the School of Engineering Science, Simon Fraser University, and co-inventor of this new technology. “In collaboration with BTG, we were able to develop a working bench prototype that demonstrates the commercial applications of the new multi-branch technology in power amplifier markets.” This new multi-branch feed-forward technology enhances the existing BTG linear amplifier portfolio. A two-branch feed-forward bench prototype of the technology, recently developed by the inventors, has been proven to deliver considerably improved linearisation bandwidth compared to existing single-branch circuits. It can also advance the distortion cancellation of today’s leading power amplifier products.
