Description
Skyworks SKY65045-70LF is a high-performance, ultrawideband
Power Amplifier (PA) driver with superior output power, low noise,
linearity, and efficiency. The device provides a 1.6 dB Noise Figure
(NF) and an output power at 1 dB compression of 25 dBm, making
the SKY65045-70LF ideal for use in the driver stage of infra-
structure transmit chains. The SKY65045-70LF is fabricated with
Skyworks high reliability Heterojunction Bipolar Transistor (HBT)
process. The device uses low-cost Surface Mount Technology
(SMT) in the form of a 2.4 x 4.5 mm Small Outline Transistor
(SOT-89) package.
The module can operate over the temperature range of -40 °C to
+85 °C. A populated evaluation board is available upon request.

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.
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
potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
