Abstract
A technique for providing an elastic RF interconnection between first and second planar conductors, which provides stress relief against mechanical and environment stresses. A length of a compressible wire bundle having first and second end portions is used as the elastic conductor. The first end portion is attached to an end of the first conductor. The second end portion is attached to an end of the second conductor. In a typical application, the first and second conductors are disposed on separate substrates, in turn mounted to a package surface.
Claims25
A method for providing a high uniformity, low VSWR RF interconnection over a broad RF frequency range, comprising:
- providing a first conductor and a second conductor in a generally coplanar relationship, the first conductor having a first connection portion, the second conductor having a second connection portion, and wherein the first connection portion is separated from the second connection portion;
- providing a length of an elastic conductor having first and second end portions, wherein the elastic conductor is a compressible wire bundle;
- attaching the first end portion to the first connection portion of the first conductor;
- and
- attaching the second end portion to the second connection portion of the second conductor.
An RF circuit, comprising:
- a first conductor and a second conductor disposed in a generally coplanar relationship, the first conductor having a first connection portion, the second conductor having a second connection portion, and wherein the first connection portion is separated from the second connection portion;
- an elastic RF interconnection between the first and second conductors, the RF interconnection for providing a high uniformity, low VSWR RF connection between the first and second conductors over a broad RF frequency range, the RF interconnection comprising an elastic conductor having first and second end portions, the first end portion attached to the first connection portion of the first conductor, the second end portion attached to the second connection portion of the second conductor, wherein the elastic conductor is a length of a compressible wire bundle.
An RF circuit, comprising:
- a first substrate mounted on a mounted surface and having a first conductor disposed on a surface of the first substrate;
- a second substrate mounted on the mounting surface spaced from the second substrate and having a second conductor disposed on a surface of the second substrate, the first and second conductors in a generally coplanar and collinear relationship;
- the first conductor having a first connection portion;
- the second conductor having a second connection portion;
- and wherein the first connection portion is separated from the second connection portion;
- an RF interconnection between the first and second conductors, the interconnection comprising a length of a compressible wire bundle having first and second end portions, the first end portion attached to the first connection portion of the first conductor, the second end portion attached to the second connection portion of the second conductor, the length of the wire bundle extending generally parallel to the first and second conductors.
