1.0 PRODUCT DESCRIPTION
SST12CP33 is a high-power, high-gain, WLAN
802.11b/g/n/256 QAM power amplifier (PA) based on
the highly-reliable InGaP/GaAs HBT technology.
This PA can be easily configured for high-power appli-
cations with high power-added efficiency while operat-
ing over the 2.4-2.5 GHz frequency band. It can
operate at both 3.3V and 5V V_CC, and typically pro-
vides 38 dB gain with 25% power-added efficiency @
P_OUT = 28 dBm for 802.11g at 5V.
SST12CP33 has excellent linearity, typically 25 dBm at
3% EVM with 54 Mbps 802.11g operation at 5V while
meeting 802.11g spectrum mask at 28 dBm and 21
dBm at 3% EVM at 3.3V bias. SST12CP33 also has a
single-ended power detector which lowers the users’
cost for power control.
The power amplifier IC also features easy board-level
usage along with high-speed power-up/-down control.
SST12CP33 is offered in 16-contact UQFN package.
See Figure 3-1 for pin assignments and Table 3-1 for
pin descriptions.
