Description

M/A-COM’s SW-395 is a GaAs monolithic 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 addi-

tion, 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, PCN,

GSM an other analog/digital wireless communications systems.

The SW-395 is fabricated using a mature 1-micron gate length

GaAs MESFET process. The process features full chip passiva-

tion for increased performance and reliability.
