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 0.5micron gate length GaAs pHEMT process. The
process features full chip passivation for increased
performance and reliability.
