Description
M/A-COM’s SW-425 is a GaAs monolithic switch in a low cost
SOT-26 surface mount plastic package. The SW-425 is ideally
suited for applications where very low power consumption
(<10µA@5V), low intermodulation products and very small size
are required. Typical applications include 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-425 can be used as a conventional T/R switch or as an antenna
diversity switch. The SW-425 can be used in power applications up
to 3 watts in systems such as celluar PCS, CDMA, W-CDMA,
TDMA, GSM and other analog/digital wireless communications
systems.
The SW-425 is fabricated using a new 0.5 micron gate length GaAs
PHEMT process. The process features full chip passivation for
increased performance and reliability.
