Abstract

A signal transition device such as a coplanar waveguide launch package is disclosed. The coplanar waveguide launch package has a first portion and a second portion. The first portion is adapted to receive electrical signals from a conductive wire. The received signals terminate proximal to a launch at a first surface of the first portion. The second portion, connected to the first portion, has a support surface at a substantially normal angle. The support surface of the second portion is adapted to support a coplanar waveguide. Because the coplanar waveguide launch package of the present invention does not require removing of bottom portions of the coplanar waveguide launch package, it does not require machining of the bottom-side, does not require removal of the bottom-side material, and does not require a bottom lid.

Claims

1. A signal transition device comprising:

a first portion adapted to receive electrical signals, the signals transferred to a launch proximal to a first surface of said first portion;

a second portion, connected to said first portion, said second portion having a support surface at a substantially normal angle compared to the first surface, said second portion adapted to support a coplanar waveguide;

wherein the first surface and said second surface define a junction; and

wherein said first portion is undercut proximal to said junction forming an overhanging ledge adapted to secure a portion of the coplanar waveguide.

2. The signal transition device recited in claim 1 further comprising a coplanar waveguide on said support surface.

3. The signal transition device recited in claim 1 wherein said first surface defines a vertical cut-out relief.

4. The signal transition device recited in claim 1 wherein said support surface defines a bottom side gap.

5. The signal transition device recited in claim 1 wherein said first portion and said second portion is machined from a single block of material.

6. A coplanar waveguide launch package comprising:

a pin terminating proximal to a first surface of the coplanar waveguide launch package, said pin adapted to carry electrical signals; and

a support surface at a substantially normal angle compared to the first surface, said support surface adapted to support a coplanar waveguide; and

wherein the first surface is undercut proximal to a line, defined by a meeting of the first surface and said support surface;

the undercut creating an overhanging ledge adapted to receive a portion of said coplanar waveguide.

7. The coplanar waveguide launch package recited in claim 6 wherein said pin and a coplanar waveguide connect at a launch.

8. The coplanar waveguide launch package recited in claim 6 further comprising a coplanar waveguide on said support surface.

9. The coplanar waveguide launch package recited in claim 6 wherein the first surface defines a vertical cut-out relief.

10. The coplanar waveguide launch package recited in claim 6 wherein said support surface defines a bottom side gap.

11. A microcircuit package comprising a coplanar waveguide launch package, the coplanar waveguide launch package comprising:

a first portion adapted to receive electrical signals, the signals transferred to a launch proximal to a first surface of said first portion;

a second portion, connected to said first portion, said second portion having a support surface forming at a substantially normal angle compared to the first surface, said second portion adapted to support a coplanar waveguide;

wherein the first surface and said second surface define a junction; and

wherein said first portion is undercut proximal to said junction forming an overhanging ledge adapted to secure a portion of the coplanar waveguide.

12. The microcircuit package recited in claim 11 further comprising a coplanar waveguide on said support surface.

13. The microcircuit package recited in claim 11 wherein said first surface defines a vertical cut-out relief.

14. The microcircuit package recited in claim 11 wherein said support surface defines a bottom side gap.

15. The microcircuit package recited in claim 11 wherein said microcircuit package is machined from a single block of material.
