A Microchip Technology Company
SST12LP08
Data Sheet
The SST12LP08 is a versatile power amplifier based on the highly-reliable InGaP/
GaAs HBT technology. Easily configured for linear high-power applications with
excellent power-added efficiency while operating over the 2.4- 2.5 GHz frequency
band, it typically provides 30 dB gain with 34% power-added efficiency, while
meeting 802.11b/g spectrum mask at 23.5 dBm. The SST12LP08 also features
easy board-level usage along with high-speed power-up/down control through a
single combined reference voltage pin and is offered in both 12-contact XQFN
and 6-contact XSON packages.

Product Description
Data Sheet
The SST12LP08 is a versatile power amplifier based on the highly-reliable InGaP/GaAs HBT technology.
The SST12LP08 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. It typically provides 30 dB gain with 34%
power-added efficiency (PAE) @ POUT = 23.5 dBm for 802.11b/g.
The SST12LP08 has excellent linearity, typically ~3% added EVM at 20 dBm output power which is
essential for 54 Mbps 802.11g operation while meeting 802.11g spectrum mask at 23.5 dBm.
The SST12LP08 can also be easily configured for high-efficiency operation, typically ~3% added EVM
at 18 dBm output power and 95 mA total power consumption for 54 Mbps 802.11g applications. High-
efficiency operation is desirable in embedded applications, such as in hand-held units, where
SST12LP08 can provide 30 dB gain and meet 802.11b/g spectrum mask at 22 dBm output power with
34% PAE.
The SST12LP08 also features easy board-level usage along with high-speed power-up/down control
through a single combined reference voltage pin. Ultra-low reference current (total IREF ~2 mA) makes
the SST12LP08 controllable by an on/off switching signal directly from the baseband chip. These fea-
tures coupled with low operating current make the SST12LP08 ideal for the final stage power amplifi-
cation in battery-powered 802.11b/g/n WLAN transmitter applications.
The SST12LP08 has an excellent on-chip, single-ended power detector, which features wide-range
(>15 dB) with dB-wise linearization. The excellent on-chip power detector provides a reliable solution
to board-level power control.
The SST12LP08 is offered in both 12-contact XQFN and 6-contact XSON packages. See Figure 3 for
pin assignments and Tables 1 and 2 for pin descriptions.
