Description
The AS176-59 is a GaAs FET IC SPDT switch packaged in an
MSOP-8 plastic package for low-cost, high-isolation commercial
applications. It is an ideal building block for base station dual-
band applications where synthesizer isolation is critical. Use in
conjunction with the AS165-59 SPST switch to meet GSM
synthesizer isolation requirements.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
