Description

M/A-COMs SW-229 is a connectorized SPDT switch that
features ultralow power consumption. SW-229 operates
from DC to 2 GHz, which makes it suitable for wideband
applications. This switch in packaged in a metal housing
with SMA connectors. Due to the internal driver selection

transients are 25 mV typical. This switch is ideal for
commercial applications that need to be developed quickly.
