Description
The AS225-313 is a 0.1–6 GHz PHEMT GaAs IC SPDT antenna
switch. Designed for WLAN applications, this device is capable
of switching 1 W microwave signals with 3 V control voltage
while maintaining high-linearity performance. The switch covers
the entire 802.11a, b and g frequency ranges. The low-loss, high-
isolation, high-inearity and low-cost features make this switch
ideal for Wireless LAN systems.
DC blocking capacitors (C BL ) must be supplied externally.
C BL = 15 pF.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
