Description

The MASWSS0179 is a GaAs single pole, double

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

plastic package. The MASWSS0179 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, the MASWSS0179 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.

The MASWSS0179 is fabricated using a mature 0.5-

micron gate length GaAs pHEMT process. The

process features full chip passivation for increased

performance and reliability.

2. DC blocking capacitors are not required if negative control

voltage is used.
