Product Description
The SST13LP02 is a high-efficiency, dual-band power amplifier based on the highly-reliable InGaP/GaAs HBT technology. The SST13LP02 can be easily configured for high-power applications with superb power-added efficiency while operating over the 802.11a/b/g frequency band for U.S., European, and Japanese markets (2.4-2.5 GHz and 4.95.8 GHz). The SST13LP02 has excellent linearity, typically ~4% added EVM at 19 dBm output power, which is essential for 54 Mbps 802.11g operation while meeting 802.11g spectrum mask at 22 dBm and 802.11b spectrum mask at 21.5 dBm. For 802.11a operation, the SST13LP02 has demonstrated typically ~4% added EVM at 18 dBm output power while meeting 802.11a spectrum mask at 22 dBm. The

SST13LP02 also has wide-range (>15 dB), temperaturestable (~1.5 dB over 85°C), single-ended 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 IREF <2 mA) makes the SST13LP02 controllable by an on/off switching signal directly from the baseband chip. These features, coupled with low operating current, make the SST13LP02 ideal for the final stage power amplification in both batterypowered 802.11a/b/g WLAN transmitters and access point applications. The SST13LP02 is offered in a 24-contact WQFN package. See Figure 2 for pin assignments and Table 1 for pin descriptions.
