The SST12LP14 can be easily configured for high-power, high-efficiency applications with superb power-added efficiency while operating over the 2.4~2.5 GHz frequency band. It typically provides 30 dB gain with 22% power-added efficiency P = 22 dBm for 802.11g and 27% power- OUT added efficiency P = 24 dBm for 802.11b. OUT 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 80C), sin- gle-ended/differential power detectors which lower users 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 I <4 mA) makes the SST12LP14 controllable by REF an on/off switching signal directly from the baseband chip. These features coupled with low operat- ing current make the SST12LP14 ideal for the final stage power amplification in battery-powered 802.11g/b WLAN transmitter applications. TheSST12LP14 is offered in 16-contact VQFN package. See Figure 2 for pin assignments and Table 1 for pin descriptions. 2011 Silicon Storage Technology, Inc. DS75031A 10/11 2
