Description
M/A-COM’s SW-395 is a GaAs single pole, double
throw switch in a low cost SOT-26 surface mount
plastic package. The SW-395 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 SW-395 can be
used as a conventional T/R switch or as an antenna
diversity switch. The SW-395 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 SW-395 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. For positive voltage control, external DC blocking capacitors
are required on all RF ports.
3. 0 = -8 V to 0 V, 1 = 0 V to +8 V.
4. Differential voltage, V (state 1) - V (state 0), must be +2.8 V
minimum and must not exceed +8 V.
