Description
M/A-COM’s MASWSS0039 is a GaAs PHEMT
MMIC DPDT diversity switch in a low cost 3 mm 12-
lead PQFN package. It is designed for low insertion
loss and allows for independent control and
selection of each switch path. It integrates blocking
capacitors on all RF ports and thus eliminates the
need for additional off-chip DC blocking capacitors.
The MASWSS0039 is ideally suited for applications
where very small size and low cost are required.
Typical applications are for WLAN IEEE 802.11a
systems that employ two antennas for transmit and
receive diversity. This part can be used in all
systems operating between 4.5 GHz and 6.0 GHz
requiring moderate power and diversity switching.
The MASWSS0039 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.
