2.4 GHz WLAN 802.11b,g,n, 256 QAM Power Amplifier
SST12LP15B
Data Sheet
SST12LP15B is a versatile power amplifier based on the highly-reliable InGaP/
GaAs HBT technology. Easily configured for high-linear operation meeting the
EVM requirements for 256 QAM applications, and for high-efficiency applications
with excellent power-added efficiency while operating over the 2.4- 2.5 GHz fre-
quency band. Configured for high efficiency, SST12LP15B will typically meet the
802.11g spectrum mask at 23 dBm with 270 mA. Configured for high linearity,
SST12LP15B will provide less than 2.5% EVM, up to 20 dBm, with MCS7-HT40
modulation, and less than 1.75% EVM, up to 18 dBm, with MCS9-VHT40 modula-
tion. This power amplifier also features easy board-level usage along with high-
speed power-up/down control through the reference voltage pins. The
SST12LP15B is offered in both a 3mm x 3mm, 16-contact VQFN package and a
2mm x 2mm, 12-contact XQFN package.
