VTI Instruments SM7100 4x4 20 GHz Non-Blocking Matrix, VXI Switch Module

VTI Instruments SM7100 4x4 20 GHz Non-Blocking Matrix, VXI Switch Module

Product Overview:

  • DC to 20GHz bandwidth
  • Full 4 x 4 matrix
  • Only two VXIbus card slots
  • Approximately 5 lbs
  • Uses miniature microwave relays
  • Other matrix configurations available



The SM7100 and SM7100-26 are part of the SMIPII™ family, offering the extensive control and interfacing features provided by SMIPII™. The microwave relay technology in these products has been pioneered to offer density, modularity and cost benefits not available from other VXI suppliers. 

Using the SMIPII™ family for microwave switching, the user obtains the following benefits over other similar VXI microwave switch solutions: 

Density: Up to 8 (1x6) microwave relays are housed in a double VXIbus slot, saving a complete C-Size slot. 

Weight: The miniature relay technology considerably reduces the overall weight. Ultra-light semi-rigid cabling is used maintaining total weight under 5 lbs. 

Cost: These modules have been priced to help reduce the cost of microwave switching by at least 40% from existing solutions. The relay technology employed satisfies the majority of ATE applications at considerably lower costs. 

The modules are configured as true 4 x 4 matrices, and also include relay driver lines for driving external components (25-pin front panel connector). All cable lengths per signal path are also matched to insure equal phase.
