Demand for gallium arsenide-based devices from digital cable markets will grow at a compound annual average growth rate (CAAGR) of 11% from 2007 to 2012 (from $72m to $10 9m), forecasts market research firm Strategy Analytics.

Due to the continued rollout and upgrade of networks, infrastructure will account for an increasing proportion of this markets, accounting for 57% of GaAs device demand from digital cable in 2007 and growing to 67% by 2012.

“Cable infrastructure applications, namely line amplifiers and hybrid amplifiers will continue to constitute the main demand for GaAs MMICs [monolithic microwave integrated circuits] for the next five years,” notes Asif Anwar, Strategy Analytics' GaAs service director. “These products are used in the cable infrastructure networks as system amplifiers, line extenders and fiber nodes.”

In the set-top box (STB) segment of the digital cable market, demand for GaAs will also grow, driven by the use of multiple tuners, adds Stephen Entwistle, VP of Strategy Analytics’ Strategic Technologies Practice. However, silicon technologies will continue to dominate, limiting the CAAGR for GaAs devices in such customer premises equipment (CPE) to no more than 5% over the next five years, he adds.
