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.

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances)-compliant packaging.
