PRODUCT DESCRIPTION
The SST12LP14C is a versatile power amplifier based on
the highly-reliable InGaP/GaAs HBT technology.
The SST12LP14C can be easily configured for high-power
applications with good power-added efficiency (PAE) while
operating over the 2.4- 2.5 GHz frequency band. It typically
provides 32 dB gain with 29% PAE @ P
OUT
= 23 dBm for
802.11g and 27% power-added efficiency @ P
OUT
= 22.5
dBm for 802.11b.
This power amplifier has excellent linearity, typically ~4%
added EVM at 20 dBm output power. This is essential for
54 Mbps 802.11g operation while meeting 802.11g spec-
trum mask up to 23 dBm.
The SST12LP14C 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 SST12LP14C control-
lable by an on/off switching signal directly from the base-
band chip. These features coupled with low operating
current make the this device ideal for the final stage power
amplification in battery-powered 802.11b/g WLAN transmit-
ter applications.
This power amplifier has an excellent on-chip and single-
ended power detector, which features a wide range
(>15 dB) with dB-wise linearization and high stability over
temperature (+/-0.5 dB 0擄C to +85擄C), and over frequency
(<+/-0.3 dB across Channels 1 through 14). The on-chip
power detector provides a reliable solution to board-level
power control.
The SST12LP14C is offered in 16-contact VQFN package.
See Figure 2 for pin assignments and Table 1 for pin
descriptions.
