2.4 GHz High-Power and High-Gain Power Amplifier
SST12LP15A
Data Sheet
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 effi-
ciency @ 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
