Sunnyvale, C.A., SST Communications announced two new power amplifiers (PAs) for 802.11a and 802.11b/g WLAN systems. The products are optimized for high linear output power and operate across -40 degrees C to +85 degrees C.. The devices' feature an on-chip temperature-stable power detector that allows system designers to optimize the transmitter output power for each individual user, thereby minimizing adjacent channel interference and optimizing capacity. The PAs are suited for WLAN equipment including PCMCIA, MiniPCI and USB cards, as well as wireless access points.
The SST12LP15 power amplifier for is designed for 802.11b/g systems. It features 35 dB gain (typical) with 26 percent power-added efficiency at +24-dBm output power for 802.11g, and 29 percent power-added efficiency at +25 dBm for 802.11b systems. Linearity is specified at approximately 4 percent added EVM (error vector magnitude) at +24-dBm output power. The on-chip power detection range is better than 25 dB (from 0 to +25 dBm), with temperature stability of +/-0.5 dB over 80 degrees C.
The SST11LP12 power amplifier supports the 802.11a frequency band for U.S., European and Japanese markets (4.9 to 5.8 GHz). It features 35 dB gain (typical) with 16 percent power-added efficiency at an output power of +23 dBm for 802.11a. Linearity is approximately 4 percent added EVM at +21-dBm output power. The on-chip power detection range is better than 23 dB (0 to +23 dBm), with temperature stability of +/-0.5 dB over 0 degrees C to 85 degrees C.
The PAs are manufactured using an InGaP/GaAs HBT technology, with tested MTTF exceeding 6x10(8) hours at 100 degrees C.
The SST12LP15 is priced at $0.72 and the SST11LP12 is priced at $1.21 each in 10,000-piece quantities. They are available now in production quantities. Click here for the SST12LP15 data sheet.
