Route signals up to 26.5 GHz through three independent SPDT 1x2 unterminated switches.


  • Three SPDT unterminated switches
  • 4 GHz, 20 GHz or 26.6 GHz options
  • High isolation loss, low VSWR
  • Up to 50 W switching
  • SMA connectors
  • External switch mounting option

The Keysight 34947A microwave switch for the 34980A Multifunction Switch/Measure Unit offers bi-directional switching for test signals from DC to 26.5 GHz. These switches provide excellent insertion loss, isolation, and VSWR specification. The microwave switches are configured as three independent 1x2 (SPDT) unterminated switches on a single module. For general-purpose microwave switching applications, the module can be used to switch separate signal sources for a multi-band receiver/transmitter testing application.
