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.
