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.
