Description

M/A-COM’s SW-395 is a GaAs single pole, double

throw switch in a low cost SOT-26 surface mount

plastic package. The SW-395 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 SW-395 can be

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

diversity switch. The SW-395 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 SW-395 is fabricated using a mature 0.5-micron

gate length GaAs PHEMT process. The process
