141 Size Family

The .141" size is the most popular because it has fairly reasonable insertion loss, is low cost and a good match with most connector types. These cables have a .036" diameter center cable conductor which can be used as the center pin of an SMA plug type connector, with the semi-rigid and conformable versions, giving mode free performance up to 35 GHz.
