Description

Skyworks SKY65028-70LF is a high performance, ultra-wideband

linear amplifier with superior output power, linearity, and efficiency.

The device is fabricated using Skyworks high reliability Aluminum

Gallium Arsenide (AlGaAs) Heterojunction Bipolar Transistor

(HBT) technology.

The SKY65028-70LF achieves a high linearity and superior

Adjacent Channel Power Rejection/Adjacent Channel Leakage Ratio

(ACPR/ACLR) performance. This makes it ideal for use in the driver

stage of infrastructure transmit chains for Trans-European Trunked

Radio (TETRA) transceivers, multi-band (GSM, AMPS, PCS, DCS)

handsets, and many other wireless applications.

The SKY65028-70LF is a lead (Pb)-free and Green SOT-89

industry standard package.

Skyworks Green products are lead (Pb)-free, RoHS

(Restriction of Hazardous Substances)-compliant,

conform to the EIA/EICTA/JEITA Joint Industry Guide

(JIG) Level A guidelines, and are free from antimony

trioxide and brominated flame retardants.
