Description
The AS230-348 is an IC FET SPDT reflective switch in a low-cost
plastic package. It features extremely high linearity, low insertion
loss, with very low DC power consumption. Some standard
implementations include antenna changeover, T/R and diversity
switching over 2 W. This switch can be used in many analog and
digital wireless communication systems.
Exposed paddle should be grounded.
DC blocking capacitors (C
BL
) are required on RF lines for positive voltage operation.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
