Sunnyvale, Calif.RF IC vendor SST Communications, a subsidiary of Silicon Storage Technology Inc. is offering a power amplifier for WiFi applications dubbed the 12LP14E, which supports the high-capacity 802.11g wireless standard and consumes 90-mA of power at 18-dBm.
The 12LP14E power amplifier's low-power consumption and 2mm x 2mm QFN packaging with a height of .45-mm make it well-suited for space-and power-constrained portable applications, such as smart phones, PDAs and handheld gaming platforms.
It also provides a low idle current of 45 mA and linearity of less than 3 percent added EVM (error vector magnitude) at 18 dBm output power, which is essential for 54-Mbits/s 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.
Pricing: $0.36 in 10,000-unit quantities.
Availability: Sampling with volume production scheduled for the fourth quarter of 2007.
