The SST12LP07A can be easily configured for high-power applications with good power-added effi- ciency while operating over the 2.4- 2.5 GHz frequency band. It typically provides 28 dB gain with 30.8% power-added efficiency P = 23.5 dBm for both 802.11g and 802.11b. OUT The SST12LP07A has excellent linearity, typically ~2.5% added EVM at 20 dBm output power which is essential for 54 Mbps 802.11g operation while meeting 802.11g spectrum mask at 23.5 dBm. The SST12LP07A also features easy board-level usage along with high-speed power-up/down control through a single combined reference voltage pin. Ultra-low reference current (total I ~2 mA) makes REF the SST12LP07A controllable by an on/off switching signal directly from the baseband chip. These fea- tures coupled with low operating current make the SST12LP07A ideal for the final stage power amplifi- cation in battery-powered 802.11g/b WLAN transmitter applications. The SST12LP07A has an excellent on-chip, single-ended power detector, which features wide-range (>15 dB) with dB-wise linearization. The excellent on-chip power detector provides a reliable solution to board-level power control. The SST12LP07A is offered in 12-contact XQFN package.
