PRODUCT DESCRIPTION
The SST12LP10 is a high-performance power amplifier
based on the highly-reliable InGaP/GaAs HBT technology.
The SST12LP10 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 provides over 26 dB gain with 19% power-added
efficiency @ POUT = 20 dBm for 802.11g and 30% power-
added efficiency @ POUT = 24 dBm for 802.11b.
The SST12LP10 has excellent linearity (over 20 dBm linear
output with total system EVM<5%) which is essential for 54
Mbps 802.11g operation.
The power amplifier IC also features easy board-level
usage along with high-speed power-up/down control and
ultra-low reference current (~3 mA). These features cou-
pled with low operating current make the SST12LP10 ideal
for the final stage power amplification in battery-powered
802.11g/b WLAN transmitter applications.
The SST12LP10 is offered in 16-contact VQFN package.
See Figure 1 for pin assignments and Table 1 for pin
descriptions.
