Description

The MASWSS0179 is a GaAs single pole, double

throw switch in a lead-free SOT-26 surface mount

plastic package and is ideally suited for applications

where very low power consumption, low

intermodulation products, very small size and low

cost are required.

Typical application is an internal / external antenna

select switch for portable telephones and data

radios. In addition, because of its low loss, good

isolation and inherent speed, this device can be

used as a conventional T/R switch or as an antenna

diversity switch. The MASWSS0179 can be used in

power applications up to 0.5 watts in systems such

as cellular, PCS, GSM and other analog / digital

wireless communications systems.

This switch is fabricated using a mature 0.5-micron

gate length GaAs pHEMT process. The process

features full chip passivation for increased

performance and reliability.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive to

electrostatic discharge (ESD) and can be damaged

by static electricity. Proper ESD control techniques

should be used when handling these devices.
