New Low-Power, Small-Footprint Power Amplifier Enables 802.11g in
Embedded Applications, Including Smart Phones, Portable Gaming
Systems and PDAs SUNNYVALE, Calif., Nov. 12 /PRNewswire-FirstCall/
-- SST Communications, a developer of RF integrated circuits and
modules for a wide range of wireless and multimedia applications
and a subsidiary of SST (Silicon Storage Technology, Inc.)
(NASDAQ:SSTI), a leader in flash memory technology, today announced
the latest addition to its high-efficiency line of power amplifiers
for WiFi applications. The new 12LP14E power amplifier supports the
high-capacity 802.11g wireless standard and features one of the
lowest power consumption specifications available on the market
today, 90mA at 18 dBm. The 12LP14E power amplifier's low power
consumption and small packaging -- a 2mm x 2mm QFN package with a
height of only .45mm -- make it a compelling solution for space-and
power-constrained portable applications, such as smart phones, PDAs
and handheld gaming platforms. "The wireless connectivity benefits
that helped WiFi revolutionize the notebook PC market are now
available in a wide range of high-volume portable consumer
electronics devices. And just as notebook PCs have migrated from
802.11b to the faster 802.11g WiFi standard, consumer electronics
devices are now looking to do the same," said Daniel Chow,
president, SST Communications. "The main obstacles designers face
when trying to incorporate 802.11g in non-notebook, embedded
consumer applications is power consumption and size. Our new
12LP14E eliminates these obstacles by providing a very
high-efficiency power amplifier in an extremely small package to
help proliferate the use of 802.11g beyond notebook PCs and into
other portable consumer electronics." In addition to its thrifty
power consumption, low idle current of 45 mA and small packaging,
the 12LP14E power amplifier has excellent linearity of less than 3
percent added EVM (error vector magnitude) at 18 dBm output power,
which is essential for 54 Mbps 802.11g operation while meeting the
standard's spectrum mask at +22 dBm min. Operating over the 2.4 to
2.5 GHz band, the 12LP14E power amplifier requires few external
components and delivers 32 percent power added efficiency (PAE) at
22 dBm output power for 802.11g, and 30 percent PAE at 21.5 dBm
output for 802.11b. Also included in the 12LP14E is an integrated
temperature stable power detector to provide a reliable solution
for power control. SST Communications' power amplifiers are
manufactured using a reliable InGaP/GaAs HBT technology, with
tested MTTF exceeding 6x10^8 hours at 100 degrees C. The company
has supplied power amplifiers to leading WLAN system vendors who
adopt WLAN transceiver solutions from companies including Atheros
and Broadcom. Pricing and Availability Samples of the 12LP14E power
amplifier are available now, with volume production scheduled for
Q4 2007. The device is priced at $0.36 in 10,000-unit quantities.
