May 4, 2007 – Growth in wireless applications should spur a 12% compound annual growth for the gallium-arsenide (GaAs) microelectronics industry over the next five years, growing from $3 billion in 2006 to more than $5 billion by 2011, according to a report from Strategy Analytics.
Wireless applications will account for more than three-quarters of all GaAs MMIC demand in 2011, with cellular handsets still the largest market for GaAs devices, the firm notes. Demand from the Wi-Fi market will grow at 28% CAGR to be the second-biggest market, with GaAs used for power amplifier (PA) functions as the market adopt 802.11n, as well as HBT PAs and pHEMT switches for PA-switch modules.
“We are seeing a variety of power amplifier (PA) approaches applied in the cellular handset front-end ranging from PA, PA-switch and PA-filter modules,” said Anwar, director of the firm’s GaAs and compound semiconductor technologies service, in a statement. He added that GaAs HBTs will dominate power amplifier applications, taking share away from Si LDMOS technology.
Demand will also heat up from the consumer segment (CATV and DBS), millimeter-wave, and fiber-optic markets, seen growing at CAGRs ranging from 6%-11% through 2011.
