PRODUCT DESCRIPTION
The SST12LP14 is a high-performance power amplifier IC
based on the highly-reliable InGaP/GaAs HBT technology.
The SST12LP14 can be easily configured for high-power,
high-efficiency applications with superb power-added effi-
ciency while operating over the 2.4~2.5 GHz frequency
band. It typically provides 30 dB gain with 22% power-
added efficiency @ POUT = 22 dBm for 802.11g and 27%
power-added efficiency @ POUT = 24 dBm for 802.11b.
The SST12LP14 has excellent linearity, typically <4%
added EVM up to 20 dBm output power which is essential
for 54 Mbps 802.11g operation while meeting 802.11g
spectrum mask at 23 dBm. The SST12LP14 also has
wide-range (>25 dB), temperature-stable (~1 dB over
80°C), single-ended/differential power detectors which
lower usersâ 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 IREF <4 mA) makes the
SST12LP14 controllable by an on/off switching signal
directly from the baseband chip. These features coupled
with low operating current make the SST12LP14 ideal for
the final stage power amplification in battery-powered
802.11g/b WLAN transmitter applications.
The SST12LP14 is offered in 16-contact VQFN package.
