| c able selection guide in order to simplify the cable selection process individual cables have been grouped into product families most flexible cable users want minimal insertion loss consistent with smallest size and weight without sacrificing flexibility other parameters will influence price and performance use the table and information below to select the cable that best suits your needs · · · cables with stranded center conductors tend to be more phase stable with flexure cables with solid center conductors tend to be more amplitude stable with flexure for applications less than 26.5 ghz start with the low loss ufa210a cable if the cable will be used in a test lab environment consider the low loss ufa210b due to its longer flex life and better phase stability with flexure if lower insertion loss is required ultra low loss ufb205a or ufb197c should be chosen if the application is less than 18 ghz choose the ultra low loss ufb311a or ufb293c if size and flexibility are critical co
