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 an-

tenna select switch for portable telephones and data

radios. In addition because of its low loss, good iso-

lation, and inherent speed, the MASWSS0143 can

be used as a conventional T/R switch or as an an-

tenna diversity switch.

The MASWSS0143 can be used in power applica-

tions 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 perform-

ance and reliability.
