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.
