PRODUCT DESCRIPTION
The SST12LP07 is a versatile power amplifier based on
the highly-reliable InGaP/GaAs HBT technology.
The SST12LP07 can be easily configured for high-power
applications with good power-added efficiency while oper-
ating over the 2.4- 2.5 GHz frequency band. This device
typically provides 29 dB gain with 22% power-added effi-
ciency @ P
OUT
= 22 dBm for 802.11g and 21% power-
added efficiency @ P
OUT
= 22 dBm for 802.11b.
The SST12LP07 has excellent linearity, typically ~2.5%
added EVM at 19 dBm output power which is essential for
54 Mbps 802.11g/n operation while meeting 802.11g spec-
trum mask at 22 dBm. The SST12LP07 can also be config-
ured for high-efficiency operation, typically 17 dBm linear 54
Mbps 802.11g output power at 85 mA total power con-
sumption. High-efficiency operation is desirable in embed-
ded applications such as in hand-held units.
The SST12LP07 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 I
REF
~2 mA) makes the SST12LP07 controlla-

ble by an on/off switching signal directly from the baseband
chip. These features coupled with low operating current
make the SST12LP07 ideal for the final stage power ampli-
fication in battery-powered 802.11g/b WLAN transmitter
applications.
The SST12LP07 has an excellent on-chip, single-ended
power detector, which features wide-range (~20 dB) with
dB-wise linearization and high stability over temperature (<
+/-0.3 dB 0擄C to +85擄C), frequency (<+/-0.3 dB across
Channels 1 through 14), and output load (<+/-0.4 dB
with 2:1 output VSWR all phases). The excellent on-
chip power detector provides a reliable solution to
board-level power control.
The SST12LP07 is offered in a 16-contact VQFN package.
