Description
M/A-COM鈥檚 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.
