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
@ POUT = 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.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via E-
mail at docerrors@microchip.com. We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. The
last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision of
silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.

The DC and RF specifications for the power amplifier
are specified below. Refer to Table 5-2 for the DC volt-
age and current specifications.
Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maxi-
mum Stress Ratings” may cause permanent damage to the device. This is a stress rating only and func-
tional operation of the device at these conditions or conditions greater than those defined in the operational
sections of this data sheet is not implied. Exposure to absolute maximum stress rating conditions may
affect device reliability.)
