Description

M/A-COM’s MASWSS0107 is a broadband GaAs

PHEMT MMIC diversity switch in a low cost, lead-

free 3 mm 12-lead PQFN package.

The

MASWSS0107 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.

The MASWSS0107 can be controlled with either two

or four control signals.

With four control signals

each of the four insertion paths can be controlled

individually.

To control the switch with only two

signals, tie pairs of control lines together.

The MASWSS0107 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full passivation for performance and

reliability.
