1. A radio frequency module comprising:
a first radio frequency component that provides a radio frequency signal;
a radio frequency transmission line including a conductive layer and a finish plating on the conductive layer, the finish plating including a gold layer having a surface that receives the radio frequency signal, a palladium layer proximate the gold layer, and a nickel layer proximate the palladium layer, the nickel layer having a thickness that is less than a skin depth of the nickel layer at 1.9 GHz; and
a second radio frequency component that receives the radio frequency signal from the first radio frequency component via at least the radio frequency transmission line.
