Power Amp Market to Double with MIMO 802.11n

Strategy Analytics reports that adoption of 802.11n MIMO with multiple transmit streams will help boost the market for Wi-Fi power amplifier modules to twice its 2008 size despite continued pricing pressure.

“As prices for single-stream 802.11n (1 x 1) chips dropped to match 802.11g, OEMs have quickly begun to switch from 802.11g to 802.11n in new products. Consequently, 802.11n will ship in more than half of all Wi-Fi systems by the end of 2010,” says Christopher Taylor, Director of the RF and Wireless Components service.

Not only will 802.11n quickly replace 802.11g, but as Wi-Fi continues to proliferate in new devices and applications, multi-stream MIMO configurations of 802.11n (i.e. 2 x 2, 3 x 3 and 4 x 4, transmit x receive) will rapidly grow in support of demand for greater range, faster file transfers and streaming multimedia in many of these applications.

SiGe Semiconductor has established a firm lead in power amplifiers despite increasing competition from GaAs PA module specialists such as Skyworks, RFMD, TriQuint and Anadigics. “A relatively small and nimble company, SiGe Semiconductor owes much of its success to concentrating its resources almost exclusively on Wi-Fi PA modules,” notes Asif Anwar, Director of the Strategy Analytics GaAs and Compound Semiconductor market research service.

I am impressed that SiGe has done well in target markets against some of these larger companies. They seem to have identified the markets that best fit their core technology.
