  • Transmission line circuit assemblies and processes for fabrication
    Patent number: 9634371
    Abstract: A transmission line circuit assembly has a substrate layer having a transmission line trace, further having a functional portion and a transitional portion. An enclosure of the assembly houses the transitional portion of the transmission line trace. A first surface of a dielectric plug is conductively coupled to an inner top surface of the enclosure. A second surface of the plug is aligned and spaced apart from the transitional portion of the transmission line trace to define a gap therebetween. An interfacing portion of a connecting pin is housed within the enclosure and bonded to the transitional portion. A connecting portion of the pin is connectable to an external conductor. The gap may be filled with a dielectric material. The transitional portion, dielectric plug, dielectric filler and connecting pin form an electromagnetic transition providing tuning and matching of the function portion with the external conductor.
