Description

The AS221-306 is a reflective SP4T switch. It is an ideal switch

for higher power applications. It can be used for GSM dual-band

handset applications where low loss, low current, and small size

are critical parameters.

DC blocking capacitors (C BL ) must be supplied externally.

C BL = 47 pF for operating frequency >500 MHz.

NEW

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances)-compliant packaging.
