Description
The SKY65111-348LF is a high-performance 3-stage, high-
power amplifier IC designed for use in 600–1100 MHz ISM band
applications such as automatic meter readers and RFID. It has an
integrated analog power control voltage for achieving the desired
output power levels. The IC is manufactured on an advanced
InGaP HBT process. The SKY65111-348LF is packaged in a ther-
mally enhanced, ultrasmall, micro lead frame package.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
Each absolute maximum rating listed is an individual parameter. Basing and driving the
amplifier with all absolute maximum ratings listed simultaneously may result in permanent
damage to the device.
CAUTION:
Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
