Description

PIN1

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.
