Description
M/A-COMs MASWSS0129 is a broadband GaAs
PHEMT MMIC diversity switch available in a low
cost, lead-free 3 mm 12-lead PQFN package. The
MASWSS0129 is ideally suited for applications
where very small size and low cost are required.
Pin Configuration
Typical applications are for WLAN IEEE 802.11a
and 802.11b/g systems that employ two antennas
Pin No. Pin Name Description
for transmit and receive diversity. Other applications
1 GND Ground
include cordless phones and base stations.
2 GND Ground
Designed for high power, this DPDT switch
maintains high linearity up to 6.0 GHz.
