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.
