PRODUCT DESCRIPTION  
The SST11LP12 is a high-power, high-gain power amplifier  
based on the highly-reliable InGaP/GaAs HBT technology.  
The power amplifier IC also features easy board-level  
usage along with high-speed power-up/down control. Ultra-  
low reference current (total IREF <3 mA) makes the  
SST11LP12 controllable by an on/off switching signal  
directly from the baseband chip. These features coupled  
with low operating current make the SST11LP12 ideal for  
the final stage power amplification in battery-powered  
802.11a WLAN transmitter and access point applications.  
The SST11LP12 can be easily configured for high-power,  
high-efficiency applications with superb power-added effi-  
ciency while operating over the entire 802.11a frequency  
band for U.S., European, and Japanese markets (4.9-5.8  
GHz). It typically provides 35 dB gain with 16% power-  
added efficiency @ POUT = 23 dBm.  
The SST11LP12 is offered in 16-contact WQFN package.  
See Figure 1 for pin assignments and Table 1 for pin  
descriptions.  
The SST11LP12 has excellent linearity, typically ~4%  
added EVM at 21 dBm output power which is essential for  
54 Mbps 802.11a operation while meeting 802.11a spec-  
trum mask at 23+ dBm. SST11LP12 also has wide-range  
(>20 dB), temperature-stable (~1 dB over 85°C), single-  
ended/differential power detectors which lower users’ cost  
on power control.
