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 4.9-
5.8 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 spec-
trum mask at 22 dBm and 802.11b spectrum mask at 21.5
dBm. For 802.11a operation, the SST13LP02 has demon-
strated 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), temperature-
stable (~1.5 dB over 85擄C), single-ended power detectors
which lower users鈥?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
REF
<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 battery-
powered 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.
