M/A-COM’s SW-337, SW-338 and SW-339 are GaAs MMIC
SPDT terminated switches in a low cost SOIC 8-lead
surface mount plastic package. They are ideally suited for
use where very low power consumption is required.
Typical applications include transmit/receive switching,
switch matrices, and filter banks in systems such as: radio
and cellular equipment, PCM, GPS, fiber optic modules,
and other battery powered radio equipment. The difference
between the switches is in the pin configuration.

The SW-337, SW-338 and SW-339 are fabricated with
monolithic GaAs MMICs using a mature 1-micron process.
The process features full chip passivation for increased
performance and reliability.
