Description

M/A-COM’s MASWSS0179 is a GaAs single pole,

double throw switch in a lead-free SOT-26 surface

mount plastic package. The MASWSS0179 is ideally

suited for applications where very low power

consumption, low intermodulation products, very small

size and low cost are required.

Typical application is an internal / external antenna

select switch for portable telephones and data radios.

In addition, because of its low loss, good isolation and

inherent speed, the MASWSS0179 can be used as a

conventional T/R switch or as an antenna diversity

switch.

The MASWSS0179 can be used in power

applications up to 0.5 Watts in systems such as

cellular, PCS, GSM and other analog / digital wireless

communications systems.

The MASWSS0179 is fabricated using a mature 0.5-

micron gate length GaAs PHEMT process. The process

features full chip passivation for increased performance

and reliability.

2. DC blocking capacitors are not required if negative control

voltage is used.
