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.
