Description
The AS172-73 is a PHEMT GaAs IC 4 port switch designed to
combine T/R and antenna changeover switching capability within
one device. This switch has two controls and is ideal for
applications requiring low power consumption. The AS172-73
has excellent performance to 2 GHz, making it suitable for
dual-band handset designs.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
