The SST12LP07 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. This device typically provides 29 dB gain with 22% power-added efficiency P = 22 dBm for 802.11g and 21% power-added effi- OUT ciency P = 22 dBm for 802.11b. OUT The SST12LP07 has excellent linearity, typically ~2.5% added EVM at 19 dBm output power which is essential for 54 Mbps 802.11g/n operation while meeting 802.11g spectrum mask at 22 dBm. The SST12LP07 can also be configured for high-efficiency operation, typically 17 dBm linear 54 Mbps 802.11g output power at 85 mA total power consumption. High-efficiency operation is desir- able in embedded applications such as in hand-held units. The SST12LP07 also features easy board-level usage along with high-speed power-up/down con- trol through a single combined reference voltage pin. Ultra-low reference current (total I ~2 mA) REF makes the SST12LP07 controllable by an on/off switching signal directly from the baseband chip. These features coupled with low operating current make the SST12LP07 ideal for the final stage power amplification in battery-powered 802.11g/b WLAN transmitter applications. The SST12LP07 has an excellent on-chip, single-ended power detector, which features wide-range (~20 dB) with dB-wise linearization and high stability over temperature (< +/-0.3 dB 0C to +85C), fre- quency (<+/-0.3 dB across Channels 1 through 14), and output load (<+/-0.4 dB with 2:1 output VSWR all phases). The excellent on-chip power detector provides a reliable solution to board-level power con- trol. The SST12LP07 is offered in a 16-contact VQFN package.
