SST Communications Launches New Power Amplifiers for Wi-Fi Applications

(Product News, 13 Nov 2007)

SST Communications, a developer of radio-frequency integrated circuits (RFICs) and modules for a wide range of wireless and multimedia applications and a subsidiary of Silicon Storage Technology Inc., has released the latest addition to its high-efficiency line of power amplifiers for Wi-Fi 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 18dBm. The 12LP14E power amplifiers come in a 2x2mm QFN package with a height of only 0.45mm—making it a compelling solution for space-and power-constrained portable applications, such as smart phones, PDAs and handheld gaming platforms.

In addition, the 12LP14E power amplifier has excellent linearity of less than 3% added EVM (error vector magnitude) at 18dBm output power, which is essential for 54Mbps 802.11g operation while meeting the standard's spectrum mask at +22dBm (min.). Operating over the 2.4GHz to 2.5GHz band, the 12LP14E power amplifier requires few external components and delivers 32% power added efficiency (PAE) at 22dBm output power for 802.11g, and 30% PAE at 21.5dBm 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°C.
