Publication number: 20130057451Abstract: This disclosure relates to a transmission line for high performance radio frequency (RF) applications. One such transmission line can include a bonding layer configured to receive an RF signal, a barrier layer, a diffusion barrier layer, and a conductive layer proximate to the diffusion barrier layer. The diffusion barrier layer can have a thickness that allows a received RF signal to penetrate the diffusion barrier layer to the conductive layer. In certain implementations, the diffusion barrier layer can be nickel. In some of these implementations, the transmission line can include a gold bonding layer, a palladium barrier layer, and a nickel diffusion barrier layer.Type: ApplicationFiled: May 4, 2012Publication date: March 7, 2013Applicant: Skyworks Solutions, Inc.Inventors: Sandra Louise Petty-Weeks, Guohao Zhang, Hardik Bhupendra Modi

Publication number: 20130057452Abstract: On a circuit board of the high-frequency module, an RF circuit and an antenna element are arranged, and transmission lines between both the RF circuit and the antenna element are provided. The transmission line of the RF circuit side among the transmission lines is led-out from the top of the circuit board to a rear surface side of the circuit board through a via hole, and the transmission line of the antenna element side is led-out from the top of the circuit board to the rear surface side through another via hole. Electrical continuity between tip portions of the transmission lines is blocked off on the rear surface of the circuit board; however, when the high-frequency module is mounted on the motherboard, a bridging connection land is soldered to each of the tip portions, so that the transmission lines are connected with each other.Type: ApplicationFiled: September 5, 2012Publication date: March 7, 2013Inventor: Hideki WATANABE
