● _{Low insertion loss}
● _{Lead (Pb)-free, RoHS-compliant, and Green}
Description
The AS218-000 is a broadband transfer switch designed to
combine T/R and antenna diversity switching functions on a
single IC. The device is designed to handle high power and
maintain high linearity at low control voltages. This low-cost
switch is ideal for Wi-Fi systems and is capable of covering both
the 2.4 and 5 GHz bands.
NEW 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.
