1.0 PRODUCT DESCRIPTION
SST12CP11C is a high-power and high-gain 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 typically
provides 37 dB gain with 25% power-added efficiency
@ P_OUT = 28 dBm for 802.11g.
SST12CP11C has excellent linearity, typically 25 dBm
at 3% EVM with 54 Mbps 802.11g operation while
meeting 802.11g spectrum mask at 28 dBm.
SST12CP11C 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.
SST12CP11C is offered in 16-contact UQFN package.
See Figure 3-1 for pin assignments and Table 4-1 for
pin descriptions.
