Description
M/A-COM’s MASWSS0094 is a broadband GaAs
PHEMT MMIC diversity switch available in a low
cost 3 mm 12-lead PQFN package or as known
good die. The MASWSS0094 is ideally suited for
applications where very small size and low cost are
required.
Typical applications are for WLAN IEEE 802.11a
and 802.11b/g systems that employ two antennas
for transmit and receive diversity. Other applications
include cordless phones and base stations.
Designed for high power, this DPDT switch
maintains high linearity up to 6.0 GHz.
