SST12LP15B datasheet, circuit
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.

SST12LP15B
Product Description
Data Sheet
SST12LP15B is a versatile power amplifier based on the highly-reliable InGaP/GaAs HBT technology.
This power amplifier can be easily configured for both high-efficiency with low EVM for high data rate
applications and for high power-added efficiency (PAE) while operating over the 2.4- 2.5 GHz fre-
quency band. There are two application circuits provided to show this versatility.
Configured for high power-added efficiency, SST12LP15B provides more than 32 dB gain and typically
meets 3% EVM up to 23 dBm output power for 54 Mbps 802.11g operation. This power amplifier also
meets spectral mask compliance output power up to 25 dBm for 802.11g and up to 25.5 dBm for
802.11b operation. At 4.5V operation, the SST12LP15B-VQFN provides up to 24 dBm at 3% EVM.
Configured for high linearity, SST12LP15B provides more than 34 dB gain. It typically meets 2.5%
EVM up to 20 dBm using MCS7-HT40 modulation and meets 1.8% EVM up to 18 dBm using MCS9-
VHT40 modulation.
This device also features easy board-level usage along with high-speed power-up/down control
through the reference voltage pins. Ultra-low reference current (total IREF ~2 mA) makes the
SST12LP15B controllable by an on/off switching signal directly from the baseband chip. These fea-
tures coupled with low operating current make SST12LP15B ideal for the final stage power amplifica-
tion in battery-powered 802.11b/g/n/256 QAM WLAN transmitter applications.
The power amplifier has an excellent, wide dynamic range (>20 dB), dB-wise linear on-chip power
detector. The excellent on-chip power detector provides a reliable solution to board-level power control.
The SST12LP15B is offered in both 16-contact VQFN (3mm x 3mm) and 12-contact XQFN (2mm x
2mm) packages. See Figures 3 and 4 for pin assignments and Tables 1 and 2 for pin descriptions.
