In Pursuit of Excellence
Through Engineering since 1978


The Series SW-218 Switches are
Broadband, High Speed, Low Loss SPST Switches

With Integral Drivers.  They are Powered by +5 and -15
Volt Supplies and are

Available Powered by ±15 Volts.  They are Available in
Three Models that Operate

Over the Entire 0.5 to 18 GHz Band.  Each Features Rugged
Integrated Circuit

Assemblies of Chip PIN on a Microstrip Transmission Line and
Proprietary Wideband

Bias Decoupling Circuitry.  Switching is Accomplished by
a TTL Compatible Driver

Which is Controlled by the User.
