Wifi Revolution

SST Communications has announced the latest addition to its high-efficiency line of power amplifiers for WiFi applications. The company’s new 12LP14E power amplifier supports the high-capacity 802.11g wireless standard and boasts one of the lowest power consumption specifications available on the market today, 90mA at 18 dBm.

 

Thanks to the 12LP14E power amplifier's low power consumption and small packaging -- a 2mm x 2mm QFN package with a height of only .45mm -- it can be used for space-and power-constrained portable applications including smart phones, PDAs and handheld gaming platforms.

 

Daniel Chow, president, SST Communications said in a statement that the wireless connectivity benefits that helped WiFi (News - Alert) revolutionize the notebook PC market are now available in a wide range of high-volume portable consumer electronics devices. Chow points out that 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.

 

Power consumption and size are the two main obstacles designers face when trying to incorporate 802.11g in non-notebook, embedded consumer applications. SST Communications, 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.

The new 12LP14E power amplifier also has excellent linearity of less than 3 percent-added EVM (error vector magnitude) at 18 dBm output power. This linearity is essential for 54 Mbps 802.11g operation and also meets the standard’s spectrum mask at +22 dBm min. The new power amplifier operates over the 2.4 to 2.5 GHz band, and requires few external components. The device 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. Moreover, as an integrated temperature stable power detector, 12LP14E provides a reliable solution for power control.

SST Communications, a subsidiary of SST (Silicon Storage Technology (News - Alert), Inc.), is a fabless semiconductor company providing optimized RF solutions to enable wireless multimedia and broadband networking system applications.
