Description

M/A-COM’s MASWSS0181 is a GaAs PHEMT

MMIC single pole two throw (SPDT) high power

switch in a lead-free SOT-26 package.

The

MASWSS0181 is ideally suited for applications

where high power, low control voltage, low insertion

loss, high isolation, small size and low cost are

required.

Typical applications are for GSM and DCS handset

systems that connect separate transmit and receive

functions to a common antenna, as well as other

related handset and general purpose applications.

This part can be used in all systems operating up to

3 GHz requiring high power at low control voltage.

The MASWSS0181 is fabricated using a 0.5 micron

gate length GaAs PHEMT process.

The process

features

full

passivation

for

performance

and

reliability.
