Claim:
1. A radio frequency module comprising: a substrate including a transmission line having a bonding layer, a barrier layer, a diffusion barrier layer, and a conductive layer, the bonding layer having a bonding surface bonded with a wire bond, the barrier layer and the diffusion barrier layer configured to prevent a contaminant from entering the bonding layer, and the diffusion barrier layer being a nickel layer having a thickness that is less than about 0.35 um so as to allow substantially all of a radio frequency signal having a frequency of at least about 1.9 GHz received at the bonding surface to propagate in the conductive layer; a first radio frequency component implemented on a die coupled to the substrate, the first radio frequency component configured to provide the radio frequency signal having the frequency of at least 1.9 GHz to the wire bond, the wire bond extending from the die to the bonding surface of the transmission line; and a second radio frequency component coupled to the substrate, the second radio frequency component configured to receive the radio frequency signal having the frequency of at least about 1.9 GHz from the first radio frequency component via the transmission line.
