"In the next five years, the market opportunities for cellular / 3G base station RF power semiconductor devices will continue to shrink," said Lance Wilson, director of market research company ABI Research. "Wireless infrastructure is the largest application area for RF power semiconductors, and it contains Sub-area: cellular / 3G. This sub-area will decline at a compound annual rate of 8% from 2007 to 2012. "The average sales price continues to fall, more efficient wireless interfaces, and the expansion of infrastructure infrastructure, turning to plastic packaging Affect the operating income.
However, the market for RF power semiconductor devices below 4GHz also includes five other important areas, namely military, ISM (Industrial / Technology / Medical), broadcasting, civil aviation and non-cellular communications. It will reach 9.5%, with the fastest growth in the military and ISM fields. Overall, the five-year growth rate of the entire market will be only 2.9%, highlighting the impact of the decline in cellular / 3G.
Some industry observers hope for WiMAX, but Wilson remains cautious: "Although fixed WiMAX is being deployed, from the perspective of high-power RF devices, the prospect of mobile WiMAX (802.16e) is still uncertain. It does have potential, but Whether this potential can be realized is still unknown. "
