Description

M/A-COM’s SW65-0003 is a GaAs MMIC SP8T reflective
switch in a SMT plastic package. The switch has a low loss
growth port, J9, that allows for cascading the device into
larger multi-throw switches. It can be configured for
common arm, J0, match when all the output ports are in
isolation. The switch offers excellent broadband
performance and repeatability from DC to 2.5 GHz, while
maintaining low DC power dissipation. The SW65-0003 is
ideally suited for switch matrix and high volume wireless
infrastructure and applications.
