Description

RF2
M/A-COM’s SW-226/227/228-PIN are GaAs MMIC
SPDT switches packaged in lead-free, surface
mount CR-2 ceramic style packages. The SW-226-
PIN is a terminated SPDT. The SW-227-PIN offers
high isolation. The SW-228-PIN offers low insertion
loss. This ceramic switch platform has a common
footprint for all three designs. The CR-2 package is
hermetically sealed, making these switches ideal for
space, military radios, and other environmentally
harsh applications.
