RE: Microwave Cables
Try a Helix cable. This is a high frequency, low loss cable suitable for taking measurements in the frequency range that you mentioned. For cable specs contact Mr. John Royer in Phoenix, Arizona, at 410-987-9713.

Thanks, Don Umbdenstock Sensormatic I have used Andrews 1/4 superflex as it is rated to 20GHz with low loss. It is not exactly flexible and more suited for permanent instalations. If you do not have to go to 25GHz then you can use their 3/8 or 1/2 for even lower loss (and less flexibility) but the high frequency performance begins to deteriorate. That particular type of coax is corugated and uses closed cell dielectric material to minimize hygroscopic affinity. Another vendor of low loss coax cables is a German manufacturer Rosenberger = Best Regards Hans Mellberg EMC Consultant __ Do You Yahoo!? Send instant messages get email alerts with Yahoo!
