PRODUCT DESCRIPTION
The SST11LP11 is a high-performance power amplifier IC
based on the highly-reliable InGaP/GaAs HBT technology.
The SST11LP11 is designed to operate over the entire
WLAN 802.11a band between 4.9-5.8 GHz frequency
band for the U.S., European, and Japanese markets while
achieving highly-linear power and low EVM.

APPLICATIONS:
• WLAN (IEEE 802.11a)
• Japan WLAN
• HyperLAN2
• Multimedia
The SST11LP11 power amplifier IC features easy board-
level usage along with on-chip linear power detection and
power-down control. These features coupled with low cur-
rent draw at maximum linear power make the SST11LP11
ideal for battery-powered 802.11a WLAN transmitter appli-
cations.
The SST11LP11 is offered in 16-contact VQFN package.
See Figure 1 for pin assignments and Table 1 for pin
descriptions.
