PRODUCT DESCRIPTION
The SST12LP15A is a high-power and high-gain power
amplifier based on the highly-reliable InGaP/GaAs HBT
technology.
The SST12LP15A can be 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 @
P
OUT
= 24 dBm for 802.11g and 27% power-added effi-
ciency @ P
OUT
= 25 dBm for 802.11b.
The SST12LP15A has excellent linearity, typically ~4%
added EVM at 23 dBm output power which is essential for
54 Mbps 802.11g operation while meeting 802.11g spec-
trum mask at 25 dBm. This device can be configured for
applications with an added EVM of approximately 3.5%, up
to 23 dBm over 2.3–2.4 GHz or 2.5–2.6 GHz WiBro/
WiMax frequency bands. SST12LP15A also has wide-
range (>25 dB), temperature-stable (~1 dB over 85°C), sin-
gle-ended/differential power detectors which lower users’
cost on power control.

The power amplifier IC also features easy board-level
usage along with high-speed power-up/down control. Ultra-
low reference current (total I
REF
~2 mA) makes the
SST12LP15A controllable by an on/off switching signal
directly from the baseband chip. These features coupled
with low operating current make the SST12LP15A ideal for
the final stage power amplification in battery-powered
802.11g/b WLAN transmitter applications.
The SST12LP15A is offered in 16-contact VQFN package.
