Description

M/A-COM’s MASWSS0028 is a GaAs PHEMT

MMIC single pole three throw (SP3T) switch in a low

cost

2mm

8-Lead

PQFN

package.

The

MASWSS0028 is ideally suited for applications

where low control voltage, low insertion loss, high

isolation, small size and low cost are required.

Typical applications are for filter and antenna

switching in handset systems that connect separate

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 low control voltage.

The MASWSS0028 is fabricated using a 0.5 micron

gate length GaAs PHEMT process.

The process

features

full

passivation

for

performance

and

reliability.
