Description
The SW-358
3
and SW-359A
4
are GaAs MMIC SPDT switches in
low cost SSOP 8-lead surface mount plastic packages.
These switches are ideally suited for use where very low distortion
and low loss are required. The SW-358 and the SW-359A can
be operated with negative, positive, or a combination of
positive/negative control voltages. 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-358 can be used as a
conventional T/R switch, or as an antenna diversity switch.
Both switches can be used for power applications up to 2 watts
in systems such as cellular, PCM, GSM, and other analog/digital
wireless communication systems.
The SW-358 and SW-359A are fabricated with monolithic GaAs
MMICs using a mature 1 micron process. The process features
full passivation for increased performance and reliability.
