Copper Mountain Technologies and Virginia Diodes Inc VDI frequency extension vector network analysis

Frequency Extension System Solution

Copper Mountain Technologies’ Cobalt 20 GHz VNAs can be used with third-party extender modules, such as Virginia Diodes, Inc. (VDI). The VDI waveguide bands below have been verified with CMT USB vector network analyzers to work with VNAX extender modules. This allows a user to test up to 330 GHz. This solution can be used for a variety of applications including antenna range measurements, material characterization, wafer s-parameter measurements, automotive radar & sensor testing, and many more applications.
Third-party extenders, including VDI extenders, only work with 20 GHz CMT VNAs and require one booster kit for 2-port VNAs (C4220) and two booster kits for 4-port VNAs (C4420). The extenders are packaged in small and versatile enclosures that allow for flexible port arrangements.
