The SST12LP15A is a high-power and high-gain power amplifier based on the highly-reliable InGaP/GaAs HBT technology. Easily configured for high-power applications with superb power-added efficiency while operating over the 2.4-2.5 GHz frequency band, it typically provides 32 dB gain with 26% power-added efficiency @ POUT = 24 dBm for 802.11g and 27% power-added efficiency @ POUT = 25 dBm for 802.11b. The SST12LP15A has excellent linearity while meeting 802.11g spectrum mask at 25 dBm. The power amplifier IC features easy board-level usage along with high-speed power-up/down control and is offered in 16-contact VQFN package.
