The SST12CP11 is a high-power and high-gain power amplifier (PA) based on the highly-reliable InGaP/GaAs HBT technology.This PA can be easily configured for high-power applications with good power-added efficiency while operating over the 2.4-2.5 GHz frequency band. It typically provides 34 dB gain and has excellent linearity, typically ~3% added EVM at 25 dBm output power, which is essential for 54 Mbps 802.11g/n operation while meeting 802.11g spectrum mask at 28.5 dBm. The power amplifier IC also features easy board-level usage along with high-speed power-up/-down control. The SST12CP11 is offered in 16-contact VQFN package.
