Description

M/A-COM’s MASWSS0143 is a GaAs monolithic switch

in a lead-free, SOT-26 surface mount plastic package.

The MASWSS0143 is ideally suited for applications

where

very

low

power

consumption,

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 MASWSS0143 can be used as a

conventional T/R switch or as an antenna diversity

switch.

The MASWSS0143 can be used in power applications

up to 3 watts in systems such as cellular PCS, CDMA,

W-CDMA, TDMA, GSM and other analog / digital

wireless communications systems.

The MASWSS0143 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full chip passivation for increased performance

and reliability.
